# bellow are programs to replace the letter "e" with "z" and vowels with "z" respectively. The first one is my original attempt which # overcomplicated things by using the find() function. All that is need is to you an if/else statement with concatination as shown in # in the second example. string = "abcdefghijklmnopqrstuvwxyz" newString = "" for i in string: pos = string.find("e") if pos == -1: newString = newString + string break newString = newString + string[:pos] + "z" string = string[pos+1:] print newString string = "abcdefghijklmnopqrstuvwxyz" newString1 = "" for i in string: if i == "e" or i == "a" or i == "i" or i == "u" or i == "o": newString1 = newString1 + "z" else: newString1 = newString1 + i print newString1 print "Done"
