Please help me add a python string to this python code to ask for vowels within the string or input.

string$\_$input $=$ input$("$Enter string: $")$

# Code responsible for counting characters

letter$\_$to$\_$count $=$ input $("$Enter a character to count in the string: $")$

character$\_$count $=$ string$\_$input.count $($letter$\_$to$\_$count$)$

# Code responsible for case conversion

words $=$ string$\_$input.split$()$ # String is split into words

upper$\_$case$\_$letter $=[$word$.$capitalize$()$ for word in words$]$ # Each first letter of each word is capitalized

title$\_$case$\_$string $=\text{'}\text{'}.$join$($upper$\_$case$\_$letter$)$ # Works are brought back together as a string

Code responsible for checking if specific initials are present

initials $=$ input$("$Enter your initials: $").$upper$()$

initials present $=$ initials in string$\_$input.upper$()$

# Code responsible for displaying results

print $($f$"$Character $\text{'}($letter$\_$to$\_$count$)\text{'}$ count in the string: $($character count$\}")$

print $($f$"$String in title case: $\{$title$\_$case$\_$string$\}")$

print $($f$"$Are your initials $(\{$initials$\})$ present in the string? $(\text{'}$Yes$\text{'}$ if initials present else $\text{'}$No$\text{'}\}")$
