10. String comparison
The relational operators work on strings. To see if two strings are equal:
if word == 'banana': print('All right, bananas.')
Other relational operations are useful for putting words in alphabetical order:
if word < 'banana': print('Your word, ' + word + ', comes before banana.') elif word > 'banana': print('Your word, ' + word + ', comes after banana.') else: print('All right, bananas.')
Python does not handle uppercase and lowercase letters the same way people do. All the uppercase letters come before all the lowercase letters, so:
Your word, Pineapple, comes before banana.
A common way to address this problem is to convert strings to a standard format, such as all lowercase, before performing the comparison. Keep that in mind in case you have to defend yourself against a man armed with a Pineapple.
