# 8.5 (Occurrences of a specified string) Write a function that counts the occurrences of a
# specified non-overlapping string s2 in another string s1 using the following header:
# def count(s1, s2):
# For example, count("system error, syntax error", "error") returns
# 2. Write a test program that prompts the user to enter two strings and displays the
# number of occurrences of the second string in the first string.
def count(s1, s2):
counter = 0
s1 = s1 + ' '
while len(s1) > 0:
s = s1[0: s1.index(' ')]
s = s[0:len(s2)]
if s == s2:
counter += 1
s1 = s1[s1.index(' ')+1: len(s1)]
return counter
def main():
str1 = input("Enter first string: ")
str2 = input("Enter second string: ")
c = count(str1, str2)
print("String", str2, "is occurred", c, "times in", str1)
main()
