THE WHILE STATEMENT
The while statement executes a set of statements repeatedly, till the logical expression evaluates
to true. When the condition becomes false, the control comes out of the loop. The syntax of while
statement is given below:

#Program to demonstrate the use of a while loop
# Initialize a variable Output
count = 1
Count is: 1
#test expression
while count < 5: Count is: 2
print("Count is:", count) Count is: 3
count += 1 Count is: 4
The While Loop Using Else Statement
