What is the result of the following expression?

s ='987654321'
print (s[-1], s[-3])
print (s[-3:], s[:-3])
print (s[-100:-3], s[-100:3])

What will be the output produced by following code fragments?

y = str(123)
x = "hello" * 3
print (x, y)
x = "hello" + "world"
y = len(x)
print (y, x)

What will be the output produced by following code fragments?

x = "hello world"
print (x[:2], x[:-2], x[-2:])
print (x[6], x[2:4])
print (x[2:-3], x[-4:-2])

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 3, what output is produced by Line 1?

1. This is a test
2. This is a
3. is a test
4. is a
5. None of these
