Why does the expression 'a'>'b' return false in Python?

Question

print('a'>'b') Returns False similar to this print('a'>'A') Returns True

Python is comparing the Unicode value of each char. 'a' = 61, 'b' = 62, and 'A' = 41. — TruBlu, Nov 09 '19 at 14:25

Python uses Lexicographical ordering for strings. This means that it uses the Unicode point number to order characters.

Python 3 uses unicode

Each character has a value according to the ASCII table:

'a' = 97

'b' = 98

'A' = 65

Which is why 97 > 98 returns false

This is incorrect. Python uses Lexicographical ordering (Unicode), not ASCII. Check my answer. – Sxribe Nov 09 '19 at 15:25
probably python 2 uses ascii? – Almog Nov 09 '19 at 17:11
OP has the `python-3.x` tag on his post. – Sxribe Nov 09 '19 at 17:50
