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. ...
In Python, ‘for loops’ are the fundamental control flow statements that are generally used to execute the particular condition in the block of code repeatedly for a fixed number of iterations. In contrast to other traditional programming languages where ‘for loops’ typically require condition ...
A for loop implements the repeated execution of code based on a loop counter or the loop variable. For loops are used when the number of iterations is known in advance. This is the structure of a basic for loop in Python: for[Temporary variable]in[sequence]: [do something] ...

Understanding the Python 'for' Loop The 'for' loop in Python is a versatile control flow tool that allows programmers to execute a block of code for a specific number of times. The key purpose of this loop, as the quiz question mentions, is to iterate over a sequence of items. This ...
