Carefully go through the code given below and answer the questions based on it :
theStr = " This is a test "
inputStr = input(" Enter integer: ")
inputlnt = int(inputStr)
testStr = theStr
while inputlnt >= 0 :
testStr = testStr[1:-1]
inputlnt = inputlnt - 1
testBool = 't' in testStr
print (theStr) # Line 1
print (testStr) # Line 2
print (inputlnt) # Line 3
print (testBool) # Line 4
Given the input integer 2, what output is produced by Line 4?
- False
- True
- 0
- 1
- None of these
Answer
Option 2 — True
Explanation
As input is 2 and inside the while loop, inputlnt decreases by 1 in each iteration so the while loop executes 3 times for inputlnt values 2, 1, 0.
1st Iteration
testStr = "This is a test"
2nd Iteration
testStr = "his is a tes"
3rd Iteration
testStr = "is is a te"
After the while loop finishes executing, value of testStr is "is is a te". 't' in testStr returns True as letter t is present in testStr.
