Introduction

In Python, a dictionary is a collection of key-value pairs. Sometimes, we may need to convert a dictionary to a list of tuples. In this challenge, you are tasked with writing a function that takes a dictionary as an argument and returns a list of tuples.

Dictionary to List

Write a function dict_to_list(d) that takes a dictionary d as an argument and returns a list of tuples. Each tuple should contain a key-value pair from the dictionary. The order of the tuples in the list should be the same as the order of the key-value pairs in the dictionary.

def dict_to_list(d):
  return list(d.items())
d = {'one': 1, 'three': 3, 'five': 5, 'two': 2, 'four': 4}
dict_to_list(d)
## [('one', 1), ('three', 3), ('five', 5), ('two', 2), ('four', 4)]

Summary

In this challenge, you learned how to convert a dictionary to a list of tuples in Python. You can use the dict.items() method to get a list of tuples from the dictionary.
