Python – Print Dictionary

Python – Print Dictionary

To print dictionary items: key:value pairs, keys, or values, you can use an iterator for the corresponding key:value pairs, keys, or values, using dict items() method, dict keys() method, or dict values() method respectively and call print() function.

In this tutorial, we will go through example programs, to print dictionary as a single string, print dictionary key:value pairs individually, print dictionary keys, and print dictionary values.

1. Print Dictionary as a single string

To print whole Dictionary contents, call print() function with dictionary passed as argument. print() converts the dictionary into a single string literal and prints to the standard console output.

In the following program, we shall initialize a dictionary and print the whole dictionary.

dictionary = {'a': 1, 'b': 2, 'c':3}
print(dictionary)

Output

{'a': 1, 'b': 2, 'c': 3}

2. Print Dictionary key:value pairs

To print Dictionary key:value pairs, use a for loop to traverse through the key:value pairs, and use print statement to print them. Dictionary items() method returns the iterator for the key:value pairs and returns key, value during each iteration.

In the following program, we shall initialize a dictionary and print the dictionary’s key:value pairs using a Python For Loop.

dictionary = {'a': 1, 'b': 2, 'c':3}

for key,value in dictionary.items():
	print(key, ':', value)

Output

a : 1
b : 2
c : 3

3. Print Dictionary keys

To print Dictionary keys, use a for loop to traverse through the dictionary keys using dictionary keys() method, and call print() function.

In the following program, we shall initialize a dictionary and print the dictionary’s keys using a Python For Loop.

dictionary = {'a': 1, 'b': 2, 'c':3}

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

Output

a
b
c

4. Print Dictionary values

To print Dictionary values, use a for loop to traverse through the dictionary values using dictionary values() method, and call print() function.

In the following program, we shall initialize a dictionary and print the dictionary’s values using a Python For Loop.

dictionary = {'a': 1, 'b': 2, 'c':3}

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

Output

1
2
3

Summary

In this tutorial, we learned how to print a dictionary using print() built-in function, print the items of dictionary using items() method, print the dictionary keys using keys() method, and print the dictionary values using values() method.
