Question
What is the output of the following Python program?
index = "Ability is a poor man's wealth".find("W")
print(index)
Question 3
Select one:
- a. 24
- b. 0
- c. 23
- d. -1
Solution
Break Down the Problem
- Identify what the Python program is doing.
- Understand the
.find()
method and its return value. - Determine the output based on the input string and the search term.
Relevant Concepts
- The
.find()
method in Python returns the lowest index of the substring if found in the string. If the substring is not found, it returns-1
.
Analysis and Detail
- The string being searched is
"Ability is a poor man's wealth"
. - The method
.find("W")
is looking for the substring"W"
(uppercase) in the given string. - Since the string does not contain an uppercase
"W"
, the.find()
method will return-1
.
Verify and Summarize
Given that the searched substring "W"
does not exist in the original string, we can verify that the result of the search will indeed be -1
.
Final Answer
The output of the program is -1
, which corresponds to option d.
