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.

--------------------------------------------------------------------------------

Find and print the number of non-alphanumeric characters.

Hint: use the len function.

Output

Check 1 passed ( I got this to pass) 

----------------------------------------------------------------------------------

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.

Hint: use the len function.

Output

3

Check 1 failed

Output: 

144 3 779

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

--------------------------------------------------------------------------------------------

Find and print all the instances of 'sit amet'

1. Using the re.findall() function, get all of the instances of 'sit amet'in the string assigned to replace_results.

2. Assign the outcome to a variable named occurrence_sit_amet.

3. Output to the console, the number of sit amet occurrences.

Hint: use the len function.
