Overview

Python dictionary items can be accessed by looping through them using a for loop.

Get all Key Names

Print all key names in the dictionary, one by one.

Method 1:

car = {
    "brand": "Maserati",
    "model": "Quattroporte",
    "year": 2025
}

for x in car:
    print(x)

Method 2: using the keys() method.

car = {
    "brand": "Maserati",
    "model": "Quattroporte",
    "year": 2025
}

for x in car.keys():
    print(x)

Output:

brand
model
year

Get all Values

Print all values in the dictionary, one by one.

Method 1:

car = {
    "brand": "Maserati",
    "model": "Quattroporte",
    "year": 2025
}

for x in car:
    print(car[x])

Method 2: using the values() method.

car = {
    "brand": "Maserati",
    "model": "Quattroporte",
    "year": 2025
}

for x in car.values():
    print(x)

Output:

Maserati
Quattroporte
2025

Get Both the Key Names and Their Values

Loop through both the keys and their values by using the items() method.

car = {
    "brand": "Maserati",
    "model": "Quattroporte",
    "year": 2025
}

for x, y in car.items():
    print(x, y)

Output:

brand Maserati
model Quattroporte
year 2025

Python Notes:

  • The most recent major version of Python is Python 3; however, Python 2 is still in use and quite popular, although not being updated with anything other than security updates
  • Python uses new lines to complete a command, as opposed to other programming languages which often use semicolons or parentheses
  • Python relies on indentation, using whitespace to define scope, such as the scope of loops, functions, and classes; other programming languages often use curly-brackets for this purpose
  • Python string methods return new values, and DO NOT change the original string
  • Python tuples are unchangeable after created (their items CANNOT be changed or re-ordered at a later point)
  • Python sets are unordered (may appear in random orders when called), unchangeable (the value of individual items cannot be changed after creation), unindexed (items cannot be referred to by index or key), and duplicates are NOT ALLOWED
  • As of v3.7, Python dictionaries are ordered and duplicates ARE ALLOWED; in v3.6 and earlier, dictionaries were unordered (did not have a defined order and could not be referred to using an index)
