Write a program that prints number of times the word "bob" occurs in a string. For example if s = "azcbobobegghakl" Then your program should print ,"Number of times 'bob' occurs is:2"

bobOccur.py

s = "azcbobobegghakl"
check = "bob"
checker = 0
for i in range(len(s)):
    try:
        if s[i] == check[0] and s[i+1] == check[1] and s[i+2] == check[2]:
            checker +=1
    except:
        pass

print "Number of times 'bob' occurs is: "+checker
