If-elif-else Statement

Sometimes, just a single test condition is not sufficient to take a decision but, it may be several other conditions
which needs to be tested in cascading order. In such situations, if…elif…else statement is used.
if<condition>:
Set of Statements
elif<condition>:
Set of statements
elif<condition>:
Set of statements
else:
Set of statements
Let us make a program using if….elif….else conditional statement in which user enters a choice.

Iterative Statement

Iterative statement or looping statement refers to those statements which are used to repeat a set of statements
for the specified number of times until a certain condition is fulfilled. As soon as the condition becomes false, the
loop terminates. These statements consist of three values:
u A starting value(i.e. initializing the starting value of a variable)

u A test expression
u A step value(Using increment or decrement operator)
In Python, the two basic type of iterative statement are as follows:

u for loop
u while loop
For Loop

The For loop statement is used to repeat itself over a range of values or sequences when the number of iterations
are known.
