Now copy the code in part $2$ and modify it to make the function replace all the alphabetic

characters in the plain$\_$text with $$m$.$ Use the functions created in part $1$ to ask the user for the

plain$\_$text to encrypt, which is $$Sunday$!$ Funyay!$$ Enter the shift value key as $4.$ The encoded

phrase encoded$\_$text will be: $$Mmmmmm$!$ Mmmmmm$!$

Page $4$ of $4$

Hints:

$$ Use is isalpha$()$ function to only convert characters and keep $!$ intact

$$ Use isupper$()$ and islower$()$ functions to use $$M$$ or $$m$$ in the replaced text
