Executing a Python File Without Specifying the Path
Instead of repeating the same solutions, here are two different ways to achieve the desired results: 1. For Mac/Linux, and for Windows using a wrapper, call a script file in order to set up a solution. 2. The sys.path is a list containing all the search paths for Python modules. The goal is to make it a «default» folder, so that each time a .py file is run, the system will automatically search this folder for the file.
How do I run python file without path?
In order to save time typing long path names, I am attempting to establish a designated folder to store all of my .py files. This folder will serve as the default location that the system will automatically search for any .py file that I attempt to run.
To avoid redundancy, I came up with a solution that involves placing my .py file in the designated module folders folder, such as «python\lib». This way, I can conveniently call it using the command «python -m filename».
However, I prefer not to create chaos within the «lib» directory.
Are there alternative methods available? Appreciated!
Based on the presence of the backslash ‘\’ in your message, I’m assuming that you’re using Windows. If my assumption is correct, then there is at least one viable solution available to you.
Generate a file named python_run.bat that resembles this one using Python.
@ECHO OFF REM *** MODIFY THE NEXT LINE TO SPECIFY THE LOCATION OF YOUR SCRIPTS *** SET SCRIPT_DIR=C:\Path\To\Scripts REM *** MODIFY THE NEXT LINE TO SPECIFY THE LOCATION OF YOUR PYTHON.EXE *** SET PYTHON_BIN=C:\Python27\python.exe PUSHD %SCRIPT_DIR% %PYTHON_BIN% %* POPD Ensure that the directory containing the python_run.bat file is included in your system’s environment variable named PATH . For instance, if the script is stored in \ \ \ \ \ C:\Path\To\Scripts\python_run\.bat\ \ \ \ , you must confirm that PATH environment variable comprises \ \ \ \ \ C:\Path\To\Scripts\ \ \ \ .
To run a script saved in your SCRIPT_DIR, all you need to do is type a specific command.
python_run my_cool_script.py --**** This will execute the command as if you were already located within your scripts folder.
C:\Python27\python.exe my_cool_script.py --**** Add your Python folder to the system path by appending the path directory «/home/****/your_python_folder/».
You have the option to bring in your own .py file.
Without a path, it is not feasible to perform the task. However, you can gather all the required modules in a single directory, which need not be placed \ \ \ \ \ python\lib\ \ \ \ but instead can be stored in a folder on your desktop. To execute the scripts, make sure to initiate them with #!/usr/bin/env python .
Import a python module without running it, In another.py, move the code that you don’t want to be ran into a block that only runs when the script is explicitly called to run and not just imported. def my_func (x): return x if __name__ == ‘__main__’: # Put that needs to run here. Now if you are in your_script.py, you can import the another module and the …
Python — add PYTHONPATH during command line module run
python somescript.py somecommand While executing this, it is necessary to include a specific directory with PYTHONPATH . Adding it to the environment variables is not a viable option as the directory changes depending on the project being run. Is it possible to modify PYTHONPATH while the script is running? It should be noted that there is no PYTHONPATH variable, so there is no concern about appending to or overriding it during the script’s execution.
PYTHONPATH=/****/baz python somescript.py somecommand Set up a wrapper for Windows using the pythonpath.bat code.
@ECHO OFF setlocal set PYTHONPATH=%1 python %2 %3 endlocal Invoke the script file with the designated pythonpath.bat identifier by making a call.
pythonpath.bat /****/baz somescript.py somecommand import sys sys.path.append('your certain directory') Essentially, sys.path serves as a collection of all the search paths for python modules , which is pre-populated by the interpreter. Additionally, the contents of PYTHONPATH are automatically appended to the end of this list.
Assuming you’re utilizing a POSIX-compliant shell, such as bash , you can establish the environment variable in the following manner:
PYTHONPATH="/path/to" python somescript.py somecommand The PYTHONPATH environment value will only have an effect on the command that is on a single line.
$ echo $PYTHONPATH $ python -c 'import sys;print("/tmp/pydir" in sys.path)' False $ PYTHONPATH=/tmp/pydir python -c 'import sys;print("/tmp/pydir" in sys.path)' True $ echo $PYTHONPATH Attempt implementing this method to execute a function within your script.
python -c "import sys; sys.path.append('/your/script/path'); import yourscript; yourscript.yourfunction()" Python: import module without executing script, If I do from someones_class import A, python would still execute the script lines in the file. Question: Is there a way to just import class A without the last two lines getting executed? I know about if __name__ == ‘__main__’ thing but I do not have the option of modifying someones_class.py file as it is obtained only …
Import Python Modules without running .Py
I wish to execute the Module without actually executing it.
main.py:
from ex import x global x call ex.py y = x+2 print y ex.py:
The code shown above is a simplified version. In this example, the variable x is used in the ex.py file, which is called when running main.py. However, the goal is to only retrieve the value of x and use it in main.py without running ex.py.
EDIT:

To provide a more comprehensive response, here’s an instance that can be cited.

The import allows access to x .
