What is sys.argv?
sys.argv is a list in Python, which contains the command-line arguments passed to the script. With the len(sys.argv) function you can count the number of arguments. If you are gonna work with command line arguments, you probably want to use sys.argv. To use sys.argv, you will first have to import the sys module.
To show how this works. (Remember that sys.argv is the name of the script.
import sys print "This is the name of the script: ", sys.argv print "Number of arguments: ", len(sys.argv) print "The arguments are: " , str(sys.argv)
This is the name of the script: sysargv.py Number of arguments in: 1 The arguments are: ['sysargv.py'] If I run it again with additional arguments, I will get this output: This is the name of the script: sysargv.py Number of arguments in: 3 The arguments are: ['sysargv.py', 'arg1', 'arg2']
