Loop Through a Dictionary

Looping through a dictionary in Python allows you to iterate over its keys, values, or key-value pairs (items) to perform various operations. There are several ways to loop through a dictionary, depending on what you want to achieve:

Loop Through Keys:

You can use a for loop to iterate through the keys of a dictionary. Here's how you do it:

my_dict = {"a": 1, "b": 2, "c": 3}
for key in my_dict:
    print(key)

This code will print the keys "a," "b," and "c."

Loop Through Values:

If you want to loop through the values of a dictionary, you can use the .values() method

my_dict = {"a": 1, "b": 2, "c": 3}
for value in my_dict.values():
    print(value)

This code will print the values 1, 2, and 3.

Loop Through Key-Value Pairs (Items):

To iterate through both the keys and values of a dictionary, you can use the .items() method:

my_dict = {"a": 1, "b": 2, "c": 3}
for key, value in my_dict.items():
    print(key, value)

This code will print key-value pairs, like "a 1," "b 2," and "c 3."

You can use the keys() method to return the keys of a dictionary.
