To temporarily set environment variables, open Command Prompt and use the set command: If no builtin module is found, Python falls back to searching in the current working directory. If this option is given, the first element of sys.argv will be the full path to the module file (while the module file is being located, the first element will be set to "-m").As with the -c option, the current directory will be added to the start of sys.path.-I option can be used to run the script in isolated mode where sys.path contains neither the current directory nor the user's site . Instead, install python and the relevant libraries from the command line using pip and then point to that python version and folders. The os.path.join() function concatenates several path components with precisely one directory separator ('/') following each non-empty part minus the last path component.If the last path segment to be joined is empty, then a directory separator ('/') is placed at the end.

A file path specifies the location of a file in the computer. Path classes are divided between pure paths, which provide purely computational operations without I/O, and concrete paths, which . For example: atom ~/.bash_profile; Step 3: To this file, add the following line at the bottom: Step 4: Save this text editor file. In the . By using a loop and the function listdir() along with rename(), we can rename multiple files at once in Python. If PYTHONPATH is set, Python will include the directories in sys.path for searching.
