Python with parameter main function

Having a parameter master function in C + + is important for writing a gadget, and recently wanted to write a parametric main function in Python as well. After the query data, the original python with parameter main function and C + + similar, simpler.

<span style= "FONT-SIZE:18PX;" >import sys
if __name__ = "__main__":
    If Len (sys.argv) = = 3:
        print sys.argv[1]
        print sys.argv[2]
        Print sys.argv[0]</span>

Here the SYS.ARGV and C + + char* argv[], using the same method.

For example:

<span style= "FONT-SIZE:18PX;" >python test.py a b
test.py</span>
