With this code, we have the variable grade and are giving it the integer value of 70.We are then using the if statement to evaluate whether or not the variable grade is greater than or equal ( >=) to 65.If it does meet this condition, we are telling the program to … IF-ELSE Statements Python. # Set x to 0 x = 0 # Check if x is type integer if type ( x) is int: print ( x, "is an integer.") 1. But while programming in Python, the conditional statement also requires enough lines of code to define the necessary condition and given code block. Q1. Example 1: The first if statement is false, so the operation to print variable “a” is not executed.
