Python Fundamentals and Programming

What will be the output?

>>>t = (1, 2)

>>>2 * t

• (1, 2, 1, 2)

• [1, 2, 1, 2]

• (1, 1, 2, 2)

• (2,4)

t = (1, 2, 4, 3, 8, 9)

print([t[i] for i in range(0, len(t), 2)])

• [2, 3, 9]

• (1, 4, 8)

• [1, 4, 8]

• [1, 2, 4, 3, 8, 9]

What is the output of the following piece of code when executed in Python shell?

>>> a=("Check")*3

>>> a

• (‘Check’,’Check’,’Check’)

• * Operator not valid for tuples

• (‘CheckCheckCheck’)

• Syntax error

What is the output of the following code?

>>> a=(2,3,4)

>>> sum(a,3)

• Too many arguments for sum() method

• The method sum() doesn’t exist for tuples

• 12

• Synatx Error

Is the following piece of code valid?

>>> a=(1,2,3,4)

>>> del a

• No because tuple is immutable

• Yes, the entire tuple is deleted

• No, invalid syntax for del method

• Yes, first element in the tuple is deleted

What type of data is: a=[(1,1),(2,4),(3,9)]?

• Array of tuples

• List of tuples

• Tuples of lists

• Invalid type

write q python function to print the sum of digits of a given number

write a python function test_prime() to find weather a given number is prime or not

write a python program to print all the prime numbers in a given range. Use the function test_prime() that you have created.

Suppose there is a list such that: l=[2,3,4].

If we want to print this list in reverse order, which of the following methods should be used?

• reverse(l)

• list(reverse[(l)])

• reversed(l)

• list(reversed(l))
