Title: Python for Loop with Range: A Comprehensive Tutorial
Introduction:
The for loop in Python is a powerful construct used for iterating over a sequence of elements. One commonly used function with for loops is range(), which generates a sequence of numbers within a specified range. In this tutorial, we'll explore the basics of the for loop and demonstrate its usage with the range() function through various examples.
Basic Syntax:
The basic syntax of a for loop in Python is as follows:
Here, variable is a placeholder that takes on the values of the elements in the sequence during each iteration.
Using range() with for loop:
The range() function generates a sequence of numbers based on the specified start, stop, and step values. The general syntax is:
Let's explore some examples:
Example 1: Simple Range Loop
Output:
Example 2: Custom Range Loop
Output:
Example 3: Iterating Over a List with Index
Output:
Example 4: Nested For Loops
Output:
Conclusion:
The combination of for loops and the range() function provides a flexible and powerful way to iterate over sequences of elements in Python. Whether you're working with simple numerical ranges or more complex data structures, mastering the for loop is fundamental for effective Python programming.
