I'm currently putting together a temperature sensor for my Raspberry Pi and ran into this issue. In order to run the driver designated in the code, I had to run it was a shell command. I'm having a difficult time figuring out why my syntax is incorrect.
Code:
def read_dht22( PiPin ):
output = subprocess.check_output([shell=True], ['/home/pi/Adafruit-Raspberry-Pi-Python-Code/Adafruit__DHT_Driver", "2302", str(PiPin)])
Error:
sudo python scr6.py
File "scr6.py", line 31
output = subprocess.check_output([shell=True], ['/home/pi/Adafruit-Raspberry-Pi-Python-Code/Adafruit_DHT_Driver', '2302', str(PiPin)])
^
SyntaxError: invalid syntax
Error Prior to Adding shell=True
sudo python scr5.py
Traceback (most recent call last):
File "scr5.py", line 46, in <module>
temp_c, temp_f = read_dht22(4)
File "scr5.py", line 31, in read_dht22
output = subprocess.check_output(["/home/pi/Adafruit-Raspberry-Pi-Python-Code/Adafruit_DHT_Driver", "2302", str(PiPin)])

File "/usr/lib/python2.7/subprocess.py", line 1259, in _execute_child
raise child_exception
OSError: [Errno 13] Permission denied
This should fix your syntax error:
def read_dht22( PiPin ):
output = subprocess.check_output(["/home/pi/Adafruit-Raspberry-Pi-Python-Code/Adafruit__DHT_Driver", "2302", str(PiPin)], shell=True)

I cannot install any pip package in my pc it returns that error

python version is : Python 3.11.1
Appreciate Your support .
I tried to install any pip package
You've installed a package PyGoogle which is very old (2006) and works only with Python 2. You need to uninstall it:
pip uninstall -y pygoogle
If that doesn't work — remove the directory C:\Users\T470\AppData\Local\Programs\Python\Python311\Lib\site-packages\pygoogle
