Yelling

No Yelling

Challenge Difficulty: Easy | Estimated completion time: ~5 minutes

Create a function that transforms sentences ending with multiple question marks ? or exclamation marks ! into a sentence only ending with one without changing punctuation in the middle of the sentences.

Examples

noYelling("What went wrong?????????")
output = "What went wrong?"
 
noYelling("Oh my goodness!!!")
output = "Oh my goodness!"
 
noYelling("I just!!! can!!! not!!! believe!!! it!!!")
output = "I just!!! can!!! not!!! believe!!! it!"
# Only change repeating punctuation at the end of the sentence.
 
noYelling("Oh my goodness!")
output = "Oh my goodness!"
# Do not change sentences where there exists only one or zero exclamation marks/question marks.

Notes

• Only change ending punctuation - keep the exclamation marks or question marks in the middle of the sentence the same (see third example).
• Don’t worry about mixed punctuation (no cases that end in something like ?!??!).
• Keep sentences that do not have question/exclamation marks the same.

Solution

Python

import re def no_yelling(text: str) -> str: """Remove repeating punctuation at the end of a sentence. Args: text: Input string Returns: String with only one ending punctuation mark """ return re.sub(r"([!?])\1+$", r"\1", text) if __name__ == "__main__": print(no_yelling("What went wrong?????????")) # What went wrong? print(no_yelling("Oh my goodness!!!")) # Oh my goodness! print(no_yelling("I just!!! can!!! not!!! believe!!! it!!!")) # I just!!! can!!! not!!! believe!!! it! print(no_yelling("Oh my goodness!")) # Oh my goodness!
