如何从 Python 环境中运行脚本？

Question

I have got recommendations to run Python script on Linux Server using this sequence:

1) source path to environment

2) python path to python script

So, I need to call this script from php command system :

Should it be like this?

system("source *path to  environment* python *path to python script*")

How to set environment and then run script?

Answer 1

system("*path/to/environment*/bin/python *path to python script*")

is enough. The trick is to run the script using python from the environment; that way you don't need to source the activation script.

Answer 2

Your python script need to contain 'shebang' string at the top #!/usr/bin/env python

for example file start.py :

#!/usr/bin/env python

def some_func():
    print("Run some python function")

if __name__ == "__main__":
    some_func()

then also you need to make it executable with command:

chmod +x start.py

and you can run it:

./start.py
