Answer: True
The `in` operator returns `True` if the left string is a substring of the right string.
Which string method checks if a string starts with a specified prefix?
Answer: startswith()
`startswith(prefix)` returns `True` if the string begins with the given prefix.
What is the result of `str(42)`?
Answer: '42'
`str()` converts an integer to its string representation, resulting in the string '42'.
What does `'Hello World'.count('l')` return?
Answer: 3
`count()` returns the number of non-overlapping occurrences; 'l' appears 3 times in 'Hello World'.
