In Python, for loops are compound statements with a header and a code block that runs a predefined number of times. The basic syntax of a for loop is shown below:Python Syntax for variable in iterable: <body> I
When programming in Python,forloops often make use of therange()sequence type as its parameters for iteration. Break statement with for loop The break statement is used to exit the for loop prematurely. It’s used to break the for loop when a specific condition is met. Let’s say we hav...

Nested Loops A nested loop is a loop inside a loop. The "inner loop" will be executed one time for each iteration of the "outer loop": Example Print each adjective for every fruit: adj = ["red","big","tasty"] fruits = ["apple","banana","cherry"] ...
The break statement terminates the for loop immediately before it loops through all the items. For example, languages = ['Swift', 'Python', 'Go', 'C++'] for lang in languages: if lang == 'Go': break print(lang) Run Code Output Swift Python Here, when lang is equal to 'Go', th...

Using for loops in Python What is a for loop? A for loop is a programming construct that allows a block of code to be executed repeatedly until a certain condition is met. The for loop works by running the code within its scope until the specified condition is no longer true, allowing ...
