I am learning Python in the hope of impressing my grandchildren - hope nobody is at all ageist! My project is to get the Hangman game I wrote in QuickBasic to work under Windows7.
I have successfuly prepared a Hangedman figure and written routine to extract random word from a large csv file. Now I want to write the user interface but attempts to return to an already used location result in overwriting - I am unable to erase the existing string.
The routine following is to explore how to write a string at a given location and erase it for the purposes of the game:
# attempt to write and erase text at point locations
# all works OK until returned to location already used
#
# 23 FEB 14
from graphics import *
import tkinter
def main():
# make window
win = GraphWin("Display text locator", 600, 500)
# click 1 to start
win.getMouse()
# establish first location
output = Text(Point(400,400),"")
output.draw(win)
# and print simulated hangman word length
output.setText(" _ _ _ _ _ _ _ _ ")
# click 2 for first string replacement
win.getMouse()
output.setText(" ABCZYX W ")
# click 3 to blank out first string
win.getMouse()
output.setText(" ")
# click 4 to show new string
win.getMouse()
output.setText(" and here we are again ")
# click 5 points to new text location and display
win.getMouse()
output = Text(Point(100,100),"")
output.draw(win)
# first string at new location
output.setText(" here's the new position ")
# click 6 to show new string
win.getMouse()
output.setText(" blank that out ")
# click 7 to erase it
win.getMouse()
output.setText(" ")
# click 8 points back to first location
win.getMouse()
output = Text(Point(400,400),"")
output.draw(win)
# should blank out existing string (but fails)
output.setText(" - ")
# click 9 to display new string (but simply overwrites)
win.getMouse()
output.setText(" BACK TO THE FIRST POSITION ")
# click 10 exits
win.getMouse()
win.close()
main()
All suggestions gratefully received (provided no laughing!)

I've been working on creating a YAML re-formatter based on ruamel.yaml (which you can see here).
I'm currently using version 0.17.20.
Cleaning up comments and whitespace has been difficult. I want to:
ensure there is only one space before the # for EOL comments
align full line comments with the key or item immediately following
remove duplicate blank lines so there is at most one blank line
To get closer to achieving that, I have a custom Emitter class where I extend write_comment to adjust the comments just before writing with super().write_comment(...). However, the Emitter does not know about which key or item comes next because comments are generally attached as post comments.
As I've studied the ruamel.yaml code to figure out how to do this, I found the rtsc mode (Round Trip Split Comments) which looks fantastic because it separates EOLComment, BlankLineComment and FullLineComment instead of lumping them together.
From what I can tell, the Parser and Scanner have been adjusted to capture the comments. So, loading is (mostly?) implemented with this "NEWCMNT" implementation. But Emitter.write_comment expects CommentToken instead of comment line numbers, so dumping does not work yet.
If I update my Emitter.write_comment method, is that enough to finish dumping? Or what else might be necessary? In one of my tries, I ran into a sys.exit in ScannedComments.assign_eol() - what else is needed to finish that?
PS: I wouldn't normally ask how to collaborate on StackOverflow, but this is not a bug report or a feature request, and I'm trying/failing to use a new (undocumented) feature, so I'm filing this here instead of sourceforge.
rtsc is work in progress cq work started but unfinished. It's internals will almost certainly change.
Two of the three points you indicate can relatively easy be implemented:
set the column of each comment to 0 ( by recursively going over a loaded data structure similar to here ) if the column is before the position of the end of the value on a line, you'll get one space between the value and the column
at the same time doing the recursion in the previous point. Take each comment value and do something like:
value = '\n'.join(line.strip() for line in value.splitlines()
while '\n\n\n' in value:
value = value.replace('\n\n\n', '\n\n')
The indentation to the following element is difficult, depends on the
data structure etc. Given that these are full line comments, I suggest
you do some postprocessing of the YAML document you generate:
find a full line comment, gather full line comments until next line is
not full line comment (i.e. some "real" YAML). Since full line comments
are in column[0] if the previous stuff is applied, you don't have to
track if you are in a (multi-line) literal or folded scalar string where
one of the lines happens to start with #
determine number of spaces
before real YAML and apply these to the full line comments.

I have a bot that writes my message to a webpage. I want the message to be sent as one paragraph, but with the lines separated by a linebreak. However, when I actually run the code, the bot inputs and enters each line separately, instead of as one paragraph

I would like for the code to output the entire text as one block of text. However, instead, it outputs as separate lines.
Output currently looks like:
FREE BABY AVOCUDDLE - Thank you for your patience!
(enters this into text box)
To redeem your FREE avocuddle, just use the LINK IN OUR BIO and ADD TO CART - just cover shipping, no additional charges!
(enters this into text box)
etc.
Instead I would like for it to send as one message.
I am struggling to find a text comparison tool or algorithm that can compare an expected text against the current state of the text being typed.
I will have an experimentee typewrite a text that he has in front of his eyes. My idea is to compare the current state of the text against the expected text whenever something is typed. That way I want to find out when and what the subject does wrong (I also want to find errors that are not in the resulting text but were in the intermediate text for some time).
Can someone point me in a direction?
Update #1
I have access to the typing data in a csv format:
This is example output data of me typing "foOBar". Every line has the form (timestamp, Key, Press/Release)

The following code does the following:
Read its content and store it in a list named steps
For each step in steps recognizes what happened and
If it was a shift press or release sets a flag (shift_on) accordingly
If it was an arrow pressed moves the cursor (index of current where we insert characters) – if it the cursor is at the start or at the end of the string it shouldn't move, that's why those min() and max()
If it was a letter/number/symbol it adds it in curret at cursor position and increments cursor
Here you have it
import csv
steps = [] # list of all actions performed by user
expected = "Hello"
with open("keyboard.csv") as csvfile:
for row in csv.reader(csvfile, delimiter=','):
steps.append((float(row[0]), row[1], row[2]))
# Now we parse the information
current = [] # text written by the user
shift_on = False # is shift pressed
cursor = 0 # where is the cursor in the current text
for step in steps:
time, key, action = step
if key == 'LeftShift':
if action == 'P':
shift_on = True
else:
shift_on = False
continue
if key == 'LeftArrow' and action == 'P':
cursor = max(0, cursor-1)
continue
if key == 'RightArrow' and action == 'P':
cursor = min(len(current), cursor+1)
continue
if action == 'P':
if shift_on is True:
current.insert(cursor, key.upper())
else:
current.insert(cursor, key.lower())
cursor += 1
# Now you can join current into a string
# and compare current with expected
print(''.join(current)) # printing current (just to see what's happening)
else:
# What to do when a key is released?
# Depends on your needs...
continue
To compare current and expected have a look here.
Note: by playing around with the code above and a few more flags you can make it recognize also symbols. This will depend on your keyboard. In mine Shift + 6 = &, AltGr + E = € and Ctrl + Shift + AltGr + è = {. I think this is a good point to start.
Update
Comparing 2 texts isn't a difficult task and you can find tons of pages on the web about it.
Anyway I wanted to present you an object oriented approach to the problem, so I added the compare part that I previously omitted in the first solution.
This is still a rough code, without primary controls over the input. But, as you asked, this is pointing you in a direction.
class UserText:
# Initialize UserText:
# - empty text
# - cursor at beginning
# - shift off
def __init__(self, expected):
self.expected = expected
self.letters = []
self.cursor = 0
self.shift = False
# compares a and b and returns a
# list containing the indices of
# mismatches between a and b
def compare(a, b):
err = []
for i in range(min(len(a), len(b))):
if a[i] != b[i]:
err.append(i)
return err
# Parse a command given in the
# form (time, key, action)
def parse(self, command):
time, key, action = command
output = ""
if action == 'P':
if key == 'LeftShift':
self.shift = True
elif key == 'LeftArrow':
self.cursor = max(0, self.cursor - 1)
elif key == 'RightArrow':
self.cursor = min(len(self.letters), self.cursor + 1)
else:
# Else, a letter/number was pressed. Let's
# add it to self.letters in cursor position
if self.shift is True:
self.letters.insert(self.cursor, key.upper())
else:
self.letters.insert(self.cursor, key.lower())
self.cursor += 1
########## COMPARE WITH EXPECTED ##########
output += "Expected: \t" + self.expected + "\n"
output += "Current: \t" + str(self) + "\n"
errors = UserText.compare(str(self), self.expected[:len(str(self))])
output += "\t\t"
i = 0
for e in errors:
while i != e:
output += " "
i += 1
output += "^"
i += 1
output += "\n[{} errors at time {}]".format(len(errors), time)
return output
else:
if key == 'LeftShift':
self.shift = False
return output
def __str__(self):
return "".join(self.letters)
import csv
steps = [] # list of all actions performed by user
expected = "foobar"
with open("keyboard.csv") as csvfile:

steps.append((float(row[0]), row[1], row[2]))

ut = UserText(expected)

I found the solution to my own question around a year ago. Now i have time to share it with you:
In their 2003 paper 'Metrics for text entry research: An evaluation of MSD and KSPC, and a new unified error metric', R. William Soukoreff and I. Scott MacKenzie propose three major new metrics: 'total error rate', 'corrected error rate' and 'not corrected error rate'. These metrics have become well established since the publication of this paper. These are exaclty the metrics i was looking for.
If you are trying to do something similiar to what i did, e.g. compare the writing performance on different input devices this is the way to go.
I want to only display numbers in a text box that i have. At the moment my code reads the text file and adds all the code to the textbox and not only the needed text(which are numbers).
tbRecipient.Text = My.Computer.FileSystem.ReadAllText("filepath")
if anyone can point me in the right direction and let me know how i would go around this problem, that would be great.
I have a file containing:
Steve, 017876
Alan, 098578
...
I want to list only the numbers into a text box once i have got them from the file.
To do this i am using:
Dim i As Integer
For i = 0 To cbRecipients.CheckedItems.Count - 1
My.Computer.FileSystem.WriteAllText("filepath", cbRecipients.CheckedItems.Item(i) & vbCrLf, True)
Next
frmHome.myFunction()
Then under myFunction() is:
tbRecipient.Text = My.Computer.FileSystem.ReadAllText("filepath")
You can use this function:
Function GetFileColumnContents(s_Path As String, ColumnNumber As Long, ColumnDelimiter As String, Optional s_OutputDelimiter As String) As String
On Error GoTo ErrHandler
Open s_Path For Input As #1 'Open the txt file for readin as Temporary File Number 1
Do While Not EOF(1) 'Read line bu line until end of file
Line Input #1, Mystring 'Store the line value in Mystring
GetFileColumnContents = GetFileColumnContents & s_OutputDelimiter & Split(Mystring, ColumnDelimiter)(ColumnNumber - 1) 'process the string
Loop
ErrHandler:
Close #1
End Function
Call in subrutine:
tbRecipient.Text = GetFileColumnContents("filepath", 2, ",", vbCrLf)
Edit: The linenum = linenum + 1 was not neccesary in the function (edited above)
s_Path : is path to the txt file (like "C:\Test.txt")
ColumnNumber: is the column in the text file. If the data looks like:
A, 123, red
B, 456, blue
then ColumnNumber 1 are letters, ColumnNumber 2 are numbers and 3 are colors.
(ColumnNumber - 1) is there because first part of split has index 0, but the ColumnNumber is 1
split("A, 123, red",",")(0) 'results to "A"
split("A, 123, red",",")(1) 'results to " 123"
If you want to list the items from text file column 2 and in the result separated by comma then call the function with comma as last argument:
tbRecipient.Text = GetFileColumnContents("filepath", 2, ",", ",")
