The Python while loop can be used to execute a block of code for as long as a certain condition is fulfilled. While loops are primarily used in Python when the number of iterations can’t be determined at the time of writing the code. Keep reading to find out how the Python while ...
While Loop In Python A while statement iterates a block of code till the controlling expression evaluates to True. While loop favors indefinite iteration, which means we don't specify how many times the loop will run in advance. In Python, a basic while loop looks like this: ...
The for loop in python is used to iterate over a given sequence. The sequence can be a string, a list, a tuple,a set, a dictionary, etc. As long as the length of the sequence is not reached, it will iterate over that sequence. The for loop contains initialization, the test expressi...

In Python, we use awhileloop to repeat a block of code until a certain condition is met. For example, number =1whilenumber <=3:print(number) number = number +1 Output 1 2 3 In the above example, we have used awhileloop to print the numbers from1to3. The loop runs as long as...
In Python,whileloops are constructed like so: while[a conditionisTrue]:[do something] Copy The something that is being done will continue to be executed until the condition that is being assessed is no longer true. Let’s create a small program that executes awhileloop. In this program, ...
