[Tutor] Fahrenheit to Celsius Conversion with if else statements

[William Gan]

Good day Alan,

Very much thanks for your guidance.

I have added or 'c' to the if statement. That is resolved.

Through that correction I discovered my C to F code was wrong. The + 32 is supposed to be executed at the end.

Thanks again. Cheers

Note this only t5ests for 'C' - ie capital C.
You might want to force the input to be uppercase first?

if unit.upper() == 'C':

Note you entered lowercase 'c' not 'C'.
Very different.
