How can you not understand what maketrans function/ method does if its definition is displayed the moment you hover over it?

[andrewt]

In the "trans_table = str.maketrans('q', 'X', string.punctuation)" the first 2 argument allow an 'on the fly' character replacement - in this case "q" gets replaced by "X"

Sorry, following along with the vid or I would have used this as the example: "trans_table = str.maketrans('\n', ' ', string.punctuation)" does the job of the carriage return removal line while dumping the punctuation.

According to ChatGPT

"isdigit(): Returns True if all characters in the string are digits, and there is at least one character.
Does not consider other numeric characters such as superscripts and subscripts as digits.

isnumeric(): Returns True if all characters in the string are numeric.
Considers other numeric characters such as superscripts, subscripts, fractions, roman numerals, etc., as numeric.

Now we know Nice that the Roman Empire is still represented (just another thing the Romans gave us [obscure Python joke])
