Day 3 of Python(while loop)

Ternary operator: It is a one line way to write the if-else condition.

Syntax: True value if (condition) else False value
Ex: To find a given number is odd or even

if num%2 ==0:
    print("given number is even")
else:
    print("given number is odd")

Now, it can be written as

var = "num is even" if(num%2 ==0) else "num is odd"
print (var)

while loop: A while loop is used when you want to repeat the code until it satisfies the condition as true.

Ex: Print a number from 1 to 10

num = 1
while num<=10:
   print(num)
   num = num+1

Output:

1
2
3
4
5
6
7
8
9
10

Ex: To print a table with given variable

num = int(input("enter a number "))
var = 1
while var<=5:
   print(num*var)
   var = var+1

Output:

enter a number 3
3
6
9
12
15
