In this challenge you will use the file regex_search_challenge_student. py to: 1.Write a regular expression that will find all occurrences of: ◦regular expression ◦regular-expression ◦regular:expression ◦regular&expression In the string: This is a string to search for a regular expression like regular expression or regular-expression or regular:expression or regular&expression 2.Assign the regular expression to a variable named pattern 3.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 4.If match1 is not None print to the console the pattern used to perform the match, followed by the word 'matched' 5.Otherwise Print to the console the pattern used to perform the match, followed by the words 'did not match' 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’’’ 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 3.Using the findall() method from the re package determine if there are occurrences in search_string 4.Assign the outcome of the findall() method to a variable called match1 5.If match1 is not None: a. Print to the console the pattern used to perform the match, followed by the word ‘matched’ 6.Otherwise: a.
