Replace Multiple Words in a string

i have the foll txt: 

txt = "there was a nr opp rd bldg"

and i need to replace them with their correct spellings.. so i made a small replacement dictionary 

rep = {"rd": "road", "nr": "near","opp":"opposite","bldg":"building"}

and used the following code: 

def replace_all(text, rep):  
    for i, j in rep.iteritems():  
        text = text.replace(i, j)  
    return text 

replace_all(txt,rep)
print txt

but the output dint change.. What could be the reason?

Function replace_all changes a local variable text and then returns it.

Your mistake is not assigning the returned value into the global variable txt.

Use txt = replace_all(txt,rep), and it should solve your problem.
