Question 16: What is the output of the following program?
Explanation: As you can see the variable ‘b’ is of type integer and the variable ‘a’ is of type string. Also as Python is a strongly typed language we cannot simply concatenate an integer with a string. We have to first convert the integer variable to the type string to concatenate it with a string variable. So, trying to concatenate an integer variable to a string variable, an exception of type “TypeError” is occurred.
