Question
What is the output of the Python method call below?
"bib".find('b', 1, 2)
Question 9 Select one:
- a. 0
- b. 2
- c. -1
- d. syntax error
- e. 3
Solution
To determine the output of the Python method call "bib".find('b', 1, 2), we need to understand the parameters of the find() method.
The find() method is used to find the first occurrence of a substring within a string. It takes three parameters: the substring to search for, the starting index, and the ending index (exclusive).
In this case, the substring we are searching for is 'b', the starting index is 1, and the ending index is 2.
Since the starting index is 1 and the ending index is 2, the search will be performed within the substring 'i' of the original string 'bib'.
However, since the starting index is greater than or equal to the ending index (1 >= 2), the search range is invalid.
Therefore, the output of the method call "bib".find('b', 1, 2) will be -1.
So, the correct answer is c. -1.
