Loop 1: i = 0 while i < 100000000: i += 1 Loop 2: for n in range (0,100000000): pass Why is the first loop so much slower? I know it's a trivial example but it's piqued my interest. Is there something special about the range () function that makes it more efficient than incrementing a variable the same way? python performance benchmarking Share

Python While Loop is used to execute a block of statements repeatedly until a given condition is satisfied. When the condition becomes false, the line immediately after the loop in the program is executed. Syntax of while loop in Python while expression: statement (s) Flowchart of Python While Loop
Python while Loop
The for and while loops are used for iteration. They are used to execute a set of statements multiple times or to iterate over a collection such as a list. The for loop in python can also be used with the range () method. You can either provide both lower and upper limits or only upper limit.
Range Function In Python Explained with Examples 2022
You can use the range function in a while loop in Python to repeat a block of code a specific number of times. The range function generates a sequence of numbers, starting from 0 by default, and increments by 1 (also by default), and stops before a specified number.
Python range() Function A Complete Guide (with Examples)
Python allows us to append else statements to our loops as well. The code within the else block executes when the loop terminates. Here is the syntax: # for 'for' loops for i in # will run when loop halts. # for 'while' loops while # will run when loop halts.

An infinite loop is a loop that runs indefinitely and it only stops with external intervention or when a break statement is found. You can stop an infinite loop with CTRL + C. You can generate an infinite loop intentionally with while True. The break statement can be used to stop a while loop immediately.

Steps Problems 1. While loop while loop repeats the sequence of actions many times until some condition evaluates to False . The condition is given before the loop body and is checked before each execution of the loop body. Typically, the while loop is used when it is impossible to determine the exact number of loop iterations in advance.
