Python Data Structures (Dictionary)
Hello guys! I will mention the dictionary which is data structures in this article. I will code on Visual Studio Code. Okay, let’s start!
Dictionary
I would like to mention the features of the dictionary in Python. There are many features. These,
Key—value concepts are in the dictionary.
- {} is defined with parentheses. The key value pair is separated by commas.
- It’s unordered. Unable to access with index. Values are accessed via key.
- It’s mutable. Allows insertion and subtraction. Key’s value can change.
- It may contain different data types such as string, float, integer etc.
- Key values can be unique, value duplicated.
I want to give a simple example how you can create to dictionary.
Empty dict
I showed you how you can create to empty dictionary on Visual Code Studio. Also, you can check that I shared it as a gist on Github.
my_dict = {}
print(my_dict)
print(type(my_dict))
Output:
{}
<class 'dict'>Access to Elements
You can access elements in two different ways in the dictionary.
- [key]
- get(key)
Adding Elements
There are many ways to add elements to a dictionary. Let’s do it!
Deleting Elements
- del key
- clear()
- del dict_name
- pop(key)
- popitem()
Merging two dictionary
- update()
- **
Copying
- = operatörü
- copy()
- dict()
Thus, I finished data structures in Python. If you want to do more practice then you can check https://github.com/Selin-Y/python-projects/blob/main/Exercise%20Dictionary/Exercise_Dictionary.py my related dictionary exercises on Github.
I hope while you’re reading my article you can enjoy it!
