What is Camelcase in Python?

CamelCase is a naming convention in programming where multiple words are concatenated without spaces, and each word after the first begins with an uppercase letter. This style is commonly used for naming variables, functions, methods, and classes, particularly in languages like Python, Java, and JavaScript.

In Python:

• CamelCase is typically used for naming classes.
• For variables, functions, and method names, Python typically follows the snake_case convention, where words are separated by underscores (e.g., my_variable).

Types of CamelCase:

1. UpperCamelCase (also known as PascalCase): The first letter of each word, including the first word, is capitalized.
   • Example: MyClass, EmployeeDetails
2. lowerCamelCase: The first letter of the first word is lowercase, while the first letter of each subsequent word is uppercase.
   • Example: myVariable, calculateTotalAmount

Usage in Python:

• Classes: In Python, it’s common to use UpperCamelCase for class names.

  class MyClass:
      def __init__(self):
          self.name = "John"
  
  my_object = MyClass()
  

• Variables, Functions, and Methods: While Python uses snake_case by convention, there might be cases (especially in codebases influenced by other languages like JavaScript) where lowerCamelCase is used for variables and method names, although this is not standard practice in Python.

  def calculateTotalAmount(price, quantity):
      return price * quantity
  
  totalAmount = calculateTotalAmount(10, 5)
  

Summary:

• CamelCase is a style where each word in a variable or class name begins with an uppercase letter, with the first letter of the first word either in lowercase (lowerCamelCase) or uppercase (UpperCamelCase).
• Python convention:
  • Classes use UpperCamelCase.
  • Variables and functions use snake_case (though some use lowerCamelCase depending on project or language influences).
