one common task is iterating through their key-value pairs. In this tutorial, we will delve into various methods to loop through a dictionary in Python, exploring different aspects and providing multiple examples to help you grasp
The second loop is more explicit and readable, but it can be less efficient than the first loop because of the additional method call. Note that in both loops, you can access the dictionary values as well: Python >>> for student in students: ... print(student, "->", students[...
