In other words, range(n) tells the program, "for i = 0, every time i < n, run through the loop and add 1 to i." i is an integer that has been initialized to 0 for the purpose of the for loop. Unlike in other languages, Python doesn't use curly brackets or any other symbol...
Meaning, the loop terminates if the statement expression/ condition becomes false. This structure allows programmers to control the flow of their code and perform repetitive tasks with ease. Syntax Of For Loop In C++ for (initialization; condition; increment/decrement) {// code to be executed} ...

In such cases, use a while loop. Fixed number of times: Print the multiplication table of 2. In this case, you know how many iterations you need. Here you need 10 iterations. In such a case use for loop. for loop in Python Syntax of for loop for i in range/sequencee: statement ...
As mentioned in syntax, theinitialization, termination, and increment are optional parts, that can be controlled from other places. Or the for loop might not have all of them. For example, we can rewrite the previous example as below. We have taken out thecounterinitialization before the loop...
