Question

Something is wrong with my Code, I need my code to get last target string's position. (Homework 6 Unit 2, Udacity)

def find_last(string_search, string_target):
position = 0

while position != -1:
position = string_search.find(string_target)
string_search = string_search[ position:]
end_pos = position

return end_pos


print find_last("kaaa","a")

Answer 1

Example: print find_last("aaaa","a") => 3

i edited it and it's much better now but it won't work if the target string is at 0

Answer 3

that's easy to fix; just define end_pos to be -1 before the while loop begins so that if the target string simply doesn't exist, you won't get an error like: http://ideone.com/JiqgL

To get it to work when it is at 0, you can assign position to the result of the find method and assign end_pos the value of position before the loop http://ideone.com/KoLT1
