Data Structures in Python? - with practical example
Data Structures in Python are used to store and organize data in a way that makes it easy to access and manipulate. There are several built-in data structures in Python such as lists, tuples, dictionaries, and sets.
Example 1: Using Lists
Lists are one of the most commonly used data structures in Python. They are ordered, mutable, and can contain elements of different data types.
Step 1: Creating a list
Step 2: Accessing elements in a list
Step 3: Adding elements to a list
Example 2: Using Dictionaries Dictionaries are another useful data structure in Python that store data in key-value pairs. Step 1: Creating a dictionary
Step 2: Accessing values in a dictionary
Step 3: Modifying values in a dictionary
By using different data structures in Python, you can efficiently manage and manipulate data in your programs.
fruits = ['apple', 'banana', 'orange', 'grape']
Step 2: Accessing elements in a list
print(fruits[1]) # Output: banana
Step 3: Adding elements to a list
fruits.append('kiwi') print(fruits) # Output: ['apple', 'banana', 'orange', 'grape', 'kiwi']
Example 2: Using Dictionaries Dictionaries are another useful data structure in Python that store data in key-value pairs. Step 1: Creating a dictionary
person = {'name': 'John', 'age': 30, 'city': 'New York'}
Step 2: Accessing values in a dictionary
print(person['age']) # Output: 30
Step 3: Modifying values in a dictionary
person['age'] = 35 print(person) # Output: {'name': 'John', 'age': 35, 'city': 'New York'}
By using different data structures in Python, you can efficiently manage and manipulate data in your programs.
