In this post, we will see how to iterate through dictionary in python.
You can use for key in dict.keys(): to iterate over keys of dictionary.
|
1 2 3 4 |
for key in dict.keys(): print(key) |
You can use for value in dict.values(): to iterate over values of dictionary.
|
1 2 3 4 |
for key in dict.values(): print(key) |
You can use items() method to iterate over key-value pairs of dictionary.
|
1 2 3 4 |
for key,value in dict.items(): print(key,":",value) |
Let’s understand with the help of example.
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 |
dict1={1:"one",2:"two",3:"three"} print("Dictionary:",dict1) print("================") print("Printing keys:") print("================") for key in dict1.keys(): print(key) print("================") print("Printing values:") print("================") for value in dict1.values(): print(value) print("============================") print("Printing key-value pairs:") print("============================") for key,value in dict1.items(): print(key,":",value) |
Output:
Dictionary: {1: ‘one’, 2: ‘two’, 3: ‘three’}
================
Printing keys:
================
1
2
3
================
Printing values:
================
one
two
three
============================
Printing key-value pairs:
============================
1 : one
2 : two
3 : three
================
Printing keys:
================
1
2
3
================
Printing values:
================
one
two
three
============================
Printing key-value pairs:
============================
1 : one
2 : two
3 : three
That’s all about iterating over dictionary in Python.
