Practice makes Perfect
Reverse


#4

def reverse(text): #1
    rev = '' #2
    count = len(text) #3
    while count > 0: #4
        rev += text[count - 1] #5
        count -= 1 #6
    return rev #7

Line 1: I defined a function reverse with the argument (text).
Line 2: rev is an empty string.
Line 3: Count is equal to length of the functions argument (text).
Line 4: While count, or the length of text, is greater than 0:
Line 5: rev (the empty string) is equal to itself plus the function argument (text)-its length minus one.
Line 6: Count is equal to itself minus one.
Line 7: It will return 'rev', the empty string that now has something in it.
Note that return does not print anything, to print you need to write 'print'. Your output should be none.
Please provide a link next time :slight_smile:
