Master Python For Loops: Syntax, Flowcharts, and Real-World Examples
This article explains Python's for‑loop syntax, visual flowcharts, multiple coding examples—including index‑based iteration and the for‑else construct—so readers can confidently iterate over lists, strings, and ranges in their own projects.
Python For Loop Overview
Python's for loop can iterate over any sequence, such as a list or a string.
Syntax
The basic syntax is: for iterating_var in sequence: followed by the statements to execute for each element.
Flowchart
Basic Example
The output of the example is shown below:
Iterating by Index
Another way to loop is by using indices with len() and range():
Here len() returns the list length and range() generates a sequence of numbers.
Using else with Loops
In Python, a for … else statement runs the else block only if the loop completes without encountering a break. The same applies to while … else.
The result of this example is:
