Do not use any built-in functions or methods such as count of str class. def countCharacter(s, char):

The function countCharacter receives a string, s and a character, char and returns the number of occurrences of this particular character.

count=0
for i in range(0,len(s)-1):
if(s[i]==char):
count=count+1;
