bash script into windows 10 powershell version - bash

Question

My Python2.7 and pypy(using virtualenv) are all under windows 10 environment. From a README file in simulation software, below includes a 'for loop" script in Bash command. How would I convert below 'for loop" (three lines) Bash commands into equivalent Windows 10 Powershell commands?
"It's better to run several processes in parallel, for instance:
$ for i in {1..10}; do
$ time $pypy epto.py conf_epto/ $i > conf_epto/run-$i.log $
$ done
And then to obtain stats for all runs:
$pypy genStats.py conf_epto 10
This will output the stats to stdout and also generate dumps in gnuplot format."
I tried to run Powershell commands but face error:
(my-pypy-env) PS C:\Users\Acer\dev\pypy27home\my-pypy-env\SimpleDA-master> for ( $i = 1; $i -le 10; $i++) {
>> $pypy epto.py conf_epto/ $i > conf_epto/run-$i.log $
>> done}
At line:2 char:7

foreach ($i in 1..10) {
Measure-Command { & $pypy epto.py conf_epto/ $i > conf_epto/run-$i.log } | Out-Host
}
& $pypy genStats.py conf_epto 10
foreach ($i in 1..10) loops over the elements of array 1..10, created with PowerShell's range operator (..); the body of compound statements such as foreach is always enclosed in { ... } in PowerShell.
Measure-Command is PowerShell's equivalent to Bash's time builtin; the command whose execution to measure is passed as a script block ({ ... }).
The command inside the script block basically works the same as in Bash, except that in Windows PowerShell > creates "Unicode" - UTF16-LE - files by default (in PowerShell Core it is UTF-8 without a BOM). > is an effective alias of the Out-File cmdlet; to use a different encoding, pipe to it and use the -Encoding parameter (e.g., ... | Out-File -Encoding utf8 conf_epto/run-$i.log), though note that in Windows PowerShell -Encoding utf8 invariably creates a UTF-8 file with a BOM.
time outputs its result directly to the terminal rather than to stdout; so does Out-Host; it bypasses PowerShell's stdout equivalent, the success [output] stream.
PowerShell requires use of &, the call operator, for executing a command whose name or path is specified as a variable ($pypy); this requirement stems from PowerShell having two distinct parsing modes.
