Regular Expression Search Challenge

Using the Python string below to perform a search using a regular expression that you create.

search_string=This is a string to search for a regular expression like regular expression or regular-expression or regular:expression or regular&expression

Write a regular expression that will find all occurrences of: a. regular expression b. regular-expression c. regular:expression d. regular&expression in search_string

Assign the regular expression to a variable named pattern

Using the findall() method from the re package determine if there are occurrences in search_string

Assign the outcome of the findall() method to a variable called match1

If match1 is not None: a. Print to the console the pattern used to perform the match, followed by the word matched

Otherwise: a. Print to the console the pattern used to perform the match, followed by the words did not match

import re #The string to search for the regular expression occurrence (This is provided to the student)

search_string='''This is a string to search for a regular expression like regular expression or regular-expression or regular:expression or regular&expression'''

#1. Write a regular expression that will find all occurrences of: # a. regular expression # b. regular-expression # c. regular:expression # d. regular&expression # in search_string #2. Assign the regular expression to a variable named pattern
