Sample Questions

1multiple correct

Which operators can be used with strings in Python?

Show answer

+ (concatenation), * (repetition), in (membership)

Strings support + for joining strings, * for repeating strings, and 'in' for checking if a substring exists. Subtraction (-) is not supported for strings.

2multiple choice

What will str1[2:5] return if str1 = 'Programming'?

Show answer

ogr

Slicing str1[2:5] starts from index 2 and ends at index 4 (5 is exclusive). In 'Programming': P=0, r=1, o=2, g=3, r=4. So indices 2, 3, 4 give 'ogr'.

3multiple correct

Which string methods return a boolean value?

Show answer

islower(), isupper(), startswith(), isalnum()

Methods like islower(), isupper(), startswith(), endswith(), isalnum() return True or False. The replace() method returns a modified string, not a boolean.

4multiple choice

What does len('Hello World!') return?

Show answer

12

The len() function counts all characters including spaces and punctuation. 'Hello World!' has 12 characters: H-e-l-l-o-space-W-o-r-l-d-!
