Question

write a program to transform a speech to a strong Scottish accent
a strong Scottish accent makes every vowel similar to an “e”,
- so you should replace every vowel with an “e”.
Additionally, it is being screamed, so it should be in block capitals.
Create a function that takes a string and returns a string.

example


to_scottish_screaming("hello world")  "HELLE WERLD"
to_scottish_screaming("Mr. Fox was very naughty")  "MR. FEX WES VERY NEEGHTY"
to_scottish_screaming("Butterflies are beautiful!")  "BETTERFLEES ERE BEEETEFEL!"
to_scottish_screaming("hello world")  "HELLE WERLD"

to_scottish_screaming("Mr. Fox was very naughty")  "MR. FEX WES VERY NEEGHTY"

to_scottish_screaming("Butterflies are beautiful!")  "BETTERFLEES ERE BEEETEFEL!"
to_scottish_screaming("hello world")  "HELLE WERLD"

to_scottish_screaming("Mr. Fox was very naughty")  "MR. FEX WES VERY NEEGHTY"

to_scottish_screaming("Butterflies are beautiful!")  "BETTERFLEES ERE BEEETEFEL!"

This fail as the scottish_scraming only replace one letter when updated.

My reflection

just keep praticing writing algorithm first to solve proble, a bit more familiar to work in this way.
re.sub() method is much simple in replace characters in a string, I should remember next time.
