Answer 1

Answer:

SCHOOLbbbbCOM

Explanation:

I am explaining it line by line, explanation is italic text, program code is bold text

define a function which takes a input, and stores input into variable named s

def fun(s):

define a variable k, which calculates and stores number of characters in s

k=len(s)

create variable named m and store empty string into it

m=" "

start a counter(i) which counts from zero to length(k) of input string(s)

for i in range(0,k):

check if character at position(i) of input(s) is upppercase

 if(s[i].isupper()):

if it's so then change uppsercase character at position(i) to lowercase, and store result into empty variable(m)

  m=m+s[i].lower()

otherwise if character at position(i) of input(s) is alphabet

 elif s[i].isalpha():

if it's so then change that alphabet character at position(i) to uppercase, and store result into variable(m)

  m=m+s[i].upper()

if none of the above conditions match, that means it's not ablphabet

 else:

then it must be a number - replace that number with 'bb' and save it into variable(m)

  m=m+'bb'

finally, print the content of variable m when counting is complete

print(m)

NOW CALL ABOVE DEFINED FUNCTION

fun('school2@com')

peww. it's long reply
