Hello

How could I get the following program to output UDP from the user entering 
user datagram protcol or IP if internet protocla was entered?

currently it only prints out on letter



import string

def main():


    phrase = (raw_input("Please enter a phrase:"))

    acr1 = string.split(phrase)
    print"",acr1 #only using print to see where I am

    acr2 = string.capwords(phrase)
    print"",acr2 #only using print to see where I am
    for phrase in string.split(phrase): 
     acronym = string.upper(phrase[0])
    
    print "", acronym
main()
