Exercise

A. Answer the following questions:
1. The input() function is used to take user input at run-time.

2. Ravita is applying arithmetic operator (+) on variable Sub1, Sub2 and Sub3. She should
convert these values to integer or float using int() or float() function. By default
input function return string value and arithmetic operation could not applied on string.

Corrected code will be :
Sub1=float(input("Enter marks of Subject1"))
Sub2= float(input("Enter marks of Subject2"))
Sub3= float(input("Enter marks of Subject3"))
Total=Sub1+Sub2+Sub3
print(Total)
3. Decision structure in programming allows you to execute statements based on a given
condition. If the condition evaluates to True, one set of statements is executed.
Otherwise, if the condition evaluates to False, another set of statements is executed.
4. The if…else statement evaluates a test expression and will execute the body of if block
only when the test condition is True. If the condition is False, the body of else block is
executed. Statements that are written at the same indent form a block.

Syntax: if<condition>:
Statements
else:
Statements
5. int() and float() functions are type conversion function. These are used to do explicit
