While loop in Python

While loop in Python Programming is a type of loop in which we pass conditions and loop continues to execute until condition is true.

What are loops?

Loops are basically use for running a same line of code multiple times. Suppose, we want to print any number(i.e, 1) multiple times(i.e, 100 times) then we don’t need to write a print statement 100 times, instead of we can use loop. We can put our single line print statement in a loop which consist a argument 100 in our case. The argument decides “How many times our code would be execute”. There are multiple types of loops in Python like for-loop, while-loop etc. Don’t worry I would tell you about every single loop in this Python Programming Series.

While-loop in Python Programming

When we want to give any condition. For example, We don’t want to terminate our loop until a condition is true. Suppose we want to print counting from 1 to 10 then we can put initialize our variable by 1. We then put a while loop with a condition(ie, run the loop until our variable is less than 11) and We would have to increment our variable in each iteration.

i=1
while(i<11):
     print(i)
     i=i+1

Here, This loop will print from 1 to 10. when our variable(i) will become 11. Our condition will become false and then loop will be end by itself.

Variable in Python Programming

Python variable is a symbolic name that is a reference or pointer to an object. Once an object is assigned to a variable, you can refer to the object by that name. But the data itself is still contained within the object. It is called variable because it’s value can be changed.
