regex='\d[0-2]-[0-1]\d-\d\d\d\d'
#test date
date="11-09-2016"
#checking if the date match the format
date_match=re.search(regex,date)
#checking if the date is in the correct format

#printing date is in the correct format
print("date is in the correct format")
else:
#printing date is not in the correct format
print("date is not in the correct format")

Write a Python program to ask user input of a string, then ask user input of what letters they want to remove from the string. User can either put in "odd", "even" or a number "n" that is greater than 2. When user input "odd", it will remove the characters which have odd numbers in the sequence of the string. When user input "even", it will remove the characters which have even numbers in the sequence of the string. When...

Write a function to check whether string s1 is a substring of string s2. The function returns the first index in s2 if there is a match. Otherwise, return -1. For example, the function should return 2 if s1 is "to" and s2 is "October". If s1 is "andy" and s2 is "candy", then the function should return 1. The function prototype is as follows: int indexOf(const char *s1, const char *s2) Write a program to test the function.
