PYTHON

A tiny Python program to check that Python is working. Try running this program from the command line like this: 

python hello.py
python hello.py Alice
That should print: 
Hello World -or- Hello Alice
Try changing the ‘Hello’ to ‘Howdy’ and run again. Once you have that working, you’re ready for class – you can edit and run Python code; now you just need to learn Python! 
import sys

# Define a main() function that prints a little greeting.

def main():

# Get the name from the command line, using 'World' as a fallback.

if len(sys.argv) >= 2:
name = sys.argv[1]
else:
name = 'World'
print 'Hello', name

# This is the standard boilerplate that calls the main() function.

if **name** == '**main**':
main()
