A manual solution could look something like this:

s = 'Hello World'

print(''.join([c.lower() if c == c.upper() else c.upper() for c in s])) # hELLO wORLD

Answer 4

If you mean just making the letters uppercase or lowercase you could use the appropriate string method

"String".upper()
"String".lower()

Perhaps I'm misunderstanding so tell me if this is the output you are looking for

a = "STRING"
b = "string"

a,b = b,a
print(a,b)
>> string STRING
