How to capitalize specific letters in string ?

Question

I want to write a function capitalizes first and fourth letters in a name like "macdonald".
I tried string.capitalize() but just first letter done and can't take arguments .
Thanks for help

Answer 1

You can do it manually, If you know it's always first and 4th then use replace method..
title() makes 'Mac Donald' if you have a space before D. Every character After a space is capitalized.. hope it helps..

x='macdonald'
y=x[0].capitalize()
z=x[3].capitalize()
print(str(y)+str(x[1:3]+str(z)+str(x[4:9])))

Answer 3

Make a `list` from the string, replace items at index 0, and 3 by their respective uppercase letter (if they were alphabets), then use str.join() method to glue `list` elements into a new string.
