Jan 9, 2024 · First one is to iterate over the sequence like List, Tuple, Set and Dictionary. And the other one is to iterate over the range of numbers. This version of for loop will iterate over a sequence of numbers using the range () function.

Jul 15, 2013 · In Python you have two fine ways to repeat some action more than once. One of them is while loop and the other - for loop. So let's have a look on two simple pieces of code: do_sth() And the other: do_sth() i += 1. My question is which of them is better.

To loop through a set of code a specified number of times, we can use the range() function, The range() function returns a sequence of numbers, starting from 0 by default, and increments by 1 (by default), and ends at a specified number.

First, initialize with loop = reversed(range(NUM_ITERATIONS+1)), then make the loop opening while next(loop):. That will produce the same values in the same order by using a reverse iterator over the range object (generating them on demand instead of eagerly up front).

Oct 10, 2020 · If you want to the program to loop the same number of times as specified in run then you can do this: run = 5 def program(run): for i in range(run): print("the number is",i) program(run)

Python’s for loop iterates over items in a data collection, allowing you to execute code for each item. To iterate from 0 to 10, you use the for index in range(11): construct. To repeat code a number of times without processing the data of an iterable, use the …

Mar 8, 2025 · Let us learn how to use for loops in Python for sequential traversals with examples. Explanation: This code prints the numbers from 0 to 3 (inclusive) using a for loop that iterates over a range from 0 to n-1 (where n = 4). We can use for loop to iterate lists, tuples, strings and dictionaries in Python.

Jan 18, 2023 · How to Use the range() Function in a for Loop in Python. If you want to loop through a set of code a specified number of times, you can use Python's built-in range() function. By default, the range() function returns a sequence of numbers starting from 0, incrementing by one, and ending at a number you specify. The syntax for this looks like this:

Apr 3, 2023 · Looping for N times in Python can be done using both the for and while loops. This tutorial will show you how to use both loops in practice. 1. Loop N times using the for loop. The most preferred method to loop N times is to use the for loop and range() function.

In this tutorial of Python Ranges, we learned how to run a For loop for specific number of times using range () function. To run a For loop for specific number of times, say n times, in Python, you can use range (n) for the iterator in the For loop syntax.
