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":

If you want to write a loop in Python which prints some integer no etc, then just copy and paste this code, it'll work a lot. print "",i,"value of loop" mydata = {"Fahim":"Pakistan", "Vedon":"China", "Bill":"USA" } . for user, country in mydata.iteritems(): print user, "belongs to " ,country.

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 …

Dec 10, 2024 · Python For Loops are used for iterating over a sequence like lists, tuples, strings, and ranges. For loop allows you to apply the same operation to every item within loop. Using For Loop avoid the need of manually managing the index. For loop can iterate over any iterable object, such as dictionary, list or any custom iterators. For Loop Example:

Mar 10, 2025 · To create a Python for loop, you start by defining an iteration variable and the iterable object you want to loop through. The iteration variable temporarily holds each item from the iterable during each loop. Then, inside the loop, you specify the actions you want to perform using this variable.

Mar 5, 2025 · Using for Loop with range() The Python range() built-in function generates a sequence of integers, often used with for loops. print (i) Output: You can also specify a start, stop, and step value. Open up your own Python editor to see for yourself: print (i) Output: Iterating Over a String. print (char) Output: Looping Through a Dictionary.

Apr 22, 2025 · In Python, loops are essential programming constructs that allow you to execute a block of code repeatedly. Among these loops, the `for` loop is one of the most versatile and commonly used. It provides a concise way to iterate over various types of sequences such as lists, tuples, strings, and even dictionaries. Understanding how to use the `for` loop effectively is crucial for writing ...

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.
