Iterating over dictionaries using 'for' loops

To iterate over a dictionary using a for loop, you can use the .items() method to get a list of the dictionary's keys and values, and then iterate over that list. Here is an example:

Iterate over a dictionary using a for loop in Python

This will output:

a 1
b 2
c 3

You can also use the .keys() method to iterate just over the keys or the .values() method to iterate just over the values. Here is an example using .keys():

Iterate over the keys of a Python dictionary

This will output:

a
b
c

And here is an example using .values():

Iterate over the values of a Python dictionary

This will output:

1
2
3
