All you need to know about Python loops
Python’s ability to handle repetitive tasks, automate processes, and implement complex algorithms through its powerful loops, is quite notable. To help Python enthusiasts fully understand loops and master their use in various scenarios, this article will cover the key features of Python loops that I believe important, the common mistakes that users often make, and how to avoid them. I’ll also share practical examples, showing how Python loops can enhance a typical predictive modeling project by streamlining processes and improving code efficiency.
Before diving into the key features of Python loops, it’s important to get familiar with various types of Python loops, as they form the foundation of today’s topic. Python offers two main types of loops: the for loop and the while loop.
For Loop
A for loop iterates over a collection of items, such as list or dictionary, and executes a block of code for each element in the collection. Here’s the syntax for a for loop:
d = {"a": 1, "b": 2, "c": 3}
for key in d:
print(key)
