Project 4 Draft: Pattern Search Introduction Your task for this project is to use regular expressions to discover and modify information from the provided test. The project is broken into two sections: Determine the number of non alpha numeric characters in the lorem_ipsum string. Replace all instances of the words sit and amet separated by a dash (-) or a colon (:) with a space. Part 1 Find and print the number of non-alphanumeric characters. Find and print the number of non-alphanumeric characters. 1. The first thing to do when doing a pattern search is to import the module re which provides full support for regular expressions in Python. This has already been provided in the code to the left. 2.Also provided for you on the left is the original string,original_text and the string,lorem_ipsum. lorem_ipsum is the string you will be using to change as you go through the programming activities in this course unit. 3.Find all of the instances of non alphanumeric characters in the string assigned to lorem_ipsum. Use the ^ and [] regular expression operator along with the findall() regular expression function. 4. Assign the outcome to a variable named results. 5.Output to the console, the number of non-alphanumeric characters. Hint: use the len function. Hint: use the len function. Expected : Output 144 Part 2: Find and print the number of 'sit' and 'amet' separated with punctuation marks 1. Using the re.findall() function, get all of the instances of 'sit-amet' or 'sit:amet' characters in the string assigned to lorem_ipsum. 2. Assign the outcome to a variable named occurrences_sit_amet 3. Output to the console, the number of sit-amet or sit:amet occurrences. Expected Output 3 Part 3: Replace 'sit' and 'amet' words separated with punctuation marks with 'sit amet' 1. Replace sit:amet and sit-amet with sit amet using the re.sub() function. 2. Assign the outcome to a variable named replace_results Part 4: Find and print all the instances of 'sit amet' Using the re.findall() function, get all of the instances of 'sit amet' in the string assigned to replace_results. Assign the outcome to a variable named occurrence_sit_amet. Output to the console, the number of sit amet occurrences. Hint: use the len function.
