Write a simple "Hello User" python code snippet.
Answer / chaitu
heloothere.py file
#!/usr/bin/env python
# import modules used here -- sys is a very standard one
import sys
# Gather our code in a main() function
def main():
print 'Hello', sys.argv[1]
# Command line args are in sys.argv[1], sys.argv[2] ...
# sys.argv[0] is the script name itself and can be ignored
# Standard boilerplate to call the main() function to begin
# the program.
if __name__ == '__main__':
main()
Running this program from the command line looks like:
$ python hello.py User
Hello User
