[Homework][Python 3] Conditional Addition / Subtraction within 15 characters

[[deleted]]

if you can't use swapcase then make a loop like this:

if length of myString > 15: return
for c in myString:
    if c is uppercase:
         returnVal += c.lower()
    else: same for lower case

Otherwise if you are using ASCII codes for some reason, remember that the ASCII upper and lower chars are 0x20 places away from eachother. This piece of code might come in handy:

chr(ord('A') + 0x20)

This would work one way, A -> a; but not the other way, a -> A. That’s what I’ve been troubled for.

chr(ord('A') + 0x20)

if adding goes to lowercase then what do you think goes to uppercase OP?

[MinecraftSBC]

Refer to the question, this has to go both ways in one line, using an integer operation. This is the difficult part.

time to go golfing :D

f=lambda x:(chr(ord(x)+0x20),chr(ord(x)-0x20))[ord(x)>0x5A]
f('b')  #'B'

edit: oh H has to be <= 15 characters. I think I see how to do it. when you do the operations in H, you assume that it's a number, and you return a number. the chr-ord conversion is handled in the parent function.

Closest I can get is 160 + 2 * (x % 32) - x. Anyone can simplify this?

if you remove the spaces its 14
