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.

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.

Feb 6, 2020 · Run the program five times using the provided first values and your chosen second values, and check your results. You can alternatively run the program once and use a for loop to execute your code five times.

With the for loop we can execute a set of statements, once for each item in a list, tuple, set etc. Print each fruit in a fruit list: The for loop does not require an indexing variable to set beforehand. Even strings are iterable objects, they contain a sequence of characters: Loop through the letters in the word "banana":

Mar 8, 2025 · In Python, a 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.

Jan 13, 2018 · To repeat something for a certain number of times, you may: # do something here. i += 1 . # do something here. _ += 1. As for nested while loops, remember to always keep the structure: j = 0.

Oct 25, 2022 · Using range () with For Loop. A for loop repeats a sequence until a condition is met. If you're familiar with other languages, you can also compare that the for loop offered by Python is more similar to the 'for-each' loop in other languages.

In this article, we will learn different types of loops in Python and discuss each of them in detail with examples. So let us begin. In programming, the loops are the constructs that repeatedly execute a piece of code based on the conditions.

In this article, we’ll take a closer look at six different approaches to calling a function N times in Python, including the use of range(), itertools.repeat(), list comprehension, for loop, map(), and while loop.

Feb 14, 2021 · We can iterate the code lines N times using the for loop with the range() function in Python. The range() function takes three parameters: start (optional): The starting value of the sequence. If not specified, the default is 0. stop: The end value of the sequence. The generated sequence will not include this value.
