some question!help - Allen - Dec-07-2018
from codebat:
Return True if the string "cat" and "dog" appear the same number of times in the given string.
cat_dog('catdog') → True
cat_dog('catcat') → False
cat_dog('1cat1cadodog') → True
here is my code:
def cat_dog(str):
for i in range(len(str)-2):
count_dog =0
count_cat=0
if str[i:i+3] == "cat":
count_cat+=1
elif str[i:i+3] =="dog":
count_dog+=1
if count_dog ==count_cat:
return True
else:
return Falsewhere is the err?

You're doing everything within the loop. You should define the count variables before the loop, update them within the loop, and then only examine them after the loop.
