Explanation:

Import string module:

The import string statement imports the built-in string module, which provides access to a collection of string constants, including string.punctuation. This constant contains a string of all common punctuation characters.

remove_punctuation function:

• This function takes a textstring as input.
• It initializes an empty string no_punct_textto store the characters without punctuation.
• It then iterates through each charin the input text.
• Inside the loop, it checks if the current charis not present in punctuation.
• If the character is not punctuation, it is appended to no_punct_text. 
• Finally, the function returns the no_punct_text
