I get an ImportError exception somewhere in the code, but the same module can be imported safely at startup of the application. I'm curious to see which paths Python looks for modules to import, so that I can trace why this problem occurs. I found this:
print sys.path
Is this the list of ALL paths that system looks when tries to import a module?

If you change __path__ , you can force the interpreter to look in a different directory for modules belonging to that package. This would allow you to, e.g., load different versions of the same module based on runtime conditions.
Step 2: If the module that needs to be imported is not found in the current directory. Then python will search it in the PYTHONPATH which is a list of directory names, with the same syntax as the shell variable PATH. To know the directories in PYTHONPATH we can simply get them by the sys module.
The path locations that python checks by default can be inspected by checking sys.path.
import sys print(sys.path) If you want a bit better formatting:
import sys from pprint import pprint pprint(sys.path) If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
