Python Program To Iterate Over Dictionaries Using For Loop - 2024

Hey guys, in this blog we will see a Python Program to Iterate Over Dictionaries Using for Loop.

Table of Contents

Example 1: Access both key and value using items()

# Python Program to Iterate Over Dictionaries Using for Loop

dt = {'a': 'messi', 'b': 'ronaldo', 'c': 'neymar'}

for key, value in dt.items():
    print(key, value)

Output

a messi
b ronaldo
c neymar

Here we have used dt.items() which will print [(‘a’,’messi’),(‘b’,’ronaldo’),(‘c’,’neymar’)].
And then we are simply every element of the list in a new line.

Example 2: Access both key and value without using items()

# Python Program to Iterate Over Dictionaries Using for Loop

dt = {'a': 'messi', 'b': 'ronaldo', 'c': 'neymar'}

for key in dt:
    print(key, dt[key])

Output

a messi
b ronaldo
c neymar

Here we are traversing in the keys of our dictionary.
Keys of our dictionary are a,b,c.
Then we are simply printing Keys and their corresponding values in the dictionary.

Example 3: Access both key and value using iteritems() (only for python 2)

# Python Program to Iterate Over Dictionaries Using for Loop

dt = {'a': 'messi', 'b': 'ronaldo', 'c': 'neymar'}

for key, value in dt.iteritems():
    print(key, value)

Output

a messi
b ronaldo
c neymar

We are using dt.iteritems() to access both keys and values of our dictionary.

Example 4: Return keys or values explicitly

# Python Program to Iterate Over Dictionaries Using for Loop

dt = {'a': 'messi', 'b': 'ronaldo', 'c': 'neymar'}

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

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

Output
