  • Find the minimum or maximum value in a list
  • Perform binary search
  • Create sorted lists of objects

How to sort lists in Python

There are several ways to sort lists in Python. The most common method is to use the sorted() function.

The sorted() function takes a list as its argument and returns a new list that is sorted in ascending order. The original list is not modified.

my_list = [5, 3, 1, 2, 4]
sorted_list = sorted(my_list)
print(sorted_list)  # [1, 2, 3, 4, 5]

sorting list in python using sorted function

You can also use the sort() method to sort a list in-place.

The sort() method does not return a new list. Instead, it modifies the original list.

my_list.sort()
print(my_list)  # [1, 2, 3, 4, 5]

sorting list in python using sort function

Customizing the sort order

By default, the sorted() and sort() functions sort lists in ascending order. However, you can customize the sort order by passing a key function to the sorted() function or the sort() method.

The key function takes an element as its argument and returns a value that is used to sort the element.

For example, the following code sorts a list of strings by their length:

my_list = ['apple', 'banana', 'cherry', 'dog', 'cat']
sorted_list = sorted(my_list, key=len)
print(sorted_list)  # ['dog', 'cat', 'apple', 'banana', 'cherry']

class in python program

What is a Class in Python?

A class in Python is a blueprint for creating objects. It defines the attributes and methods that an object will have. Classes are used to create objects that share the same characteristics and behavior.

Benefits of Using Classes

  • Encapsulation: Classes allow us to bundle data and methods together into a single unit, making it easier to manage and organize code.
  • Modularity: Classes encourage code reusability by allowing us to create templates that can be reused in different parts of a program.
  • Extensibility: Classes enable us to extend existing functionality by creating new classes that inherit from existing ones.

Creating a Class

To create a class in Python, we use the class keyword followed by the class name and a colon. Inside the class, we define the attributes and methods using the self keyword, which refers to the instance of the class.

class Person:
  def __init__(self, name, age):
    self.name = name
    self.age = age

  def get_name(self):
    return self.name

  def get_age(self):
    return self.age

Creating Objects

To create an object from a class, we use the Class() syntax. Once created, we can access the attributes and methods of the object using the dot operator.

person = Person("John", 30)
print(person.get_name())  # Output: John
print(person.get_age())  # Output: 30

Conclusion

Classes are a fundamental concept in Python programming that allow us to create reusable and extensible code. They provide a structured way to organize and manage data and behavior, making it easier to develop maintainable and scalable applications.
