Question
What is the output of the Python method call below?
"bib".find('b', 1, 2)
Question 4 Select one:
- a. 0
- b. 2
- c. -1
- d. syntax error
- e. 3
Solution
The output of the Python method call "bib".find('b', 1, 2) is -1.
Here's the step by step explanation:
-
The find() method in Python is used to find the index of a substring in a string. It returns the lowest index where the substring is found. If the substring is not found, it returns -1.
-
In the method call "bib".find('b', 1, 2), 'b' is the substring we are trying to find in the string 'bib'. The numbers 1 and 2 are the start and end indices respectively, within which we are trying to find the substring.
-
The string 'bib' has 'b' at indices 0 and 2. However, we are only looking between indices 1 and 2. Therefore, within this range, 'b' is not found.
-
Hence, the method call returns -1.
So, the correct answer is c. -1.
