How can I iterate through a dictionary in Python?

How can I iterate through a dictionary in Python?

You can iterate through a dictionary using a for loop. For example:

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

What if I only want to iterate through the keys?

You can iterate through just the keys using the keys() method:

for key in my_dict.keys():
    print(key)

Can I iterate through the values only?

Yes, you can use the values() method to iterate through the values:

for value in my_dict.values():
    print(value)

Is there a way to iterate and modify the dictionary at the same time?

It's generally not safe to modify a dictionary while iterating over it. Instead, you can create a copy of the keys or items to modify.
