Code points

Questions 1 to 5 of 6

1. 1. What does len('😀') return for a string that holds one smiling face emoji?

   1234
2. 2. Which expression returns the number of code points in a Python string s?

   len(s.encode('utf-8'))len(s.encode('utf-16-le')) // 2s.size()len(s)
3. 3. What does this program print? ``python mixed = 'a😀é' print(len(mixed)) print(len(mixed.encode('utf-16-le')) // 2) ``

   3 and 33 and 44 and 32 and 3
4. 4. What does this program print? ``python s = 'a😀b' print(s[:2]) print(len(s)) ``

   a 2a 3a😀 2a😀 3
5. 5. True or false: the string é (one code point, U+00E9) and the string e followed by U+0301 (a combining accent) look the same on screen, so == returns True when they are compared.

   False, because the two strings hold different code points, so == returns FalseTrue, because both strings look the same on screen
