if b == "ALL" or "all" :
print(register[a])
else :
print(register[a][b])

output :-

Answer 1

Make sure your TAB space is correct. "else" should be right under "if" word

Answer 2

1. if b == 'ALL' or 'all': # always True
A non empty string is truthy. So this is like doing 1 comparison and then the other side is always True. Would be the same as;
if b == 'ALL' or True:

if b == 'ALL' or b == 'all': # comparison on each side of or

Or better yet just use the lower() method

if b.lower() == 'all':

(the upper() method could be used similarly)

2. Your indentation is off and doesn't match.

if b.lower() == 'all':
print(register[a])
else:
print(register[a][b])

See how the e in else is directly below the i in if, and the p from each print() are also lined up. Their indentation matches.

EDIT: also using the str() function for the result of input() is redundant and not needed as input() already returns a str object.

Don't use;
str(input())
just use;
input()

Conversion from input() is only needed for types other than string, such as int(), float(), etc.
