Thanks Bob! :) I'm very new at programming in Python. I appreciate
your feedback.
Here are some improvements to consider:
import string
def main():
d = {"1" : phoneTranslator, "2" : backwardString} # map user
selection to corresponding function
while True:
selection = raw_input("Enter you choice. Enter 1 " +
"for Phone Translator or 2 for Backward String.")
operation = d.get(selection, None) # retrieve corresponding
function or None
if operation: # did we get something?
operation() # call it
break # out of the while loop
print "Invalid choice"
def phoneTranslator():
trans = string.maketrans("ABCDEFGHIJKLMNOPQRSTUVWXYZ",
"22233344455566677778889999")
print "Phone Translator "
phoneNumber = raw_input ("Please enter the phone number: ").upper()
phoneNumber = phoneNumber.translate(trans)
print phoneNumber[:3] + "-" + phoneNumber[3:]
def backwardString():
print "not implemented"
main()
Better yet wrap the call to main() so it's not always called when the
module gets imported, plus some error handling wouldn't go amiss. For
anyone using Python 3 raw_input becomes input and you don't need the
import string, it's simply str.maketrans(...).
