使用不同的参数值运行一个Python脚本

Question

I have a Python script called a.py , which takes 1 parameter from the command line. a.py is invoked as follows: python a.py 1 , where 1 is the parameter value. Now, suppose I run a.py with 3 different parameter values on a single machine like this:

python a.py 1 &
python a.py 2 &
python a.py 3

I only see one a.pyc file. I wonder why there is only one a.pyc file since I invoke the program 3 times with 3 different parameters values, should there be 3 a.pyc files (maybe with different names)? If not, the a.pyc file couldn't contain all 3 parameters values, so where are the parameter values (ie, 1,2,3 ) stored?

Answer 1

please refer this Difference py and pyc

Basically parameters you are passing is just a system argument. When Py file is get compiled it converted into Byte Code, Where System argument is just a input parameter from command line so there will be single Pyc file for the same code base.
