Guide Kit

String manipulation refers to the process of manipulating strings, which are sequences of characters. This can include operations like concatenation, splitting, replacement, and more. It is a common task in programming languages and can be used for different purposes: 

Data validation: String manipulation can be used to check if a string meets certain requirements, such as a valid email address or phone number. 
Text processing: String manipulation can be used to clean and preprocess text data, such as removing unwanted characters or converting all text to lowercase. 
File manipulation: String manipulation can be used to extract information from a file name or manipulating a file’s contents.

List comprehension can manipulate strings by converting them to a list of characters and then applying the desired operation. List comprehension also has other uses: 

You can also use list comprehension to filter specific characters or substrings from a string. 
You can also use list comprehension to perform other string manipulation tasks, like applying a function to every string’s character, extracting certain substrings from the string, etc.
