class variable in python

Comment

# Class variables refer to variables that are made within a class.
# It is generated when you define the class.
# It's shared with all the instance of that class.
# Example:

class some_variable_holder(object):
    
    var = "This variable is created inside the class some_variable_holder()."
    
    def somefunc(self):
        print("Random function ran.")

thing = some_variable_holder()
another_thing = some_variable_holder()

# Both does the same thing because the same variable has been passed on from the class.
thing.var
another_thing.var

python class variables

Comment

# Class definition with a class variable
class MyClass:
    # Class variable
    class_variable = "This is a class variable"

    def __init__(self):
        # Instance variable
        self.instance_variable = "This is an instance variable"

# Accessing class variable directly using the class name
print(MyClass.class_variable)

# Creating an instance of MyClass
obj = MyClass()
# Accessing class variable using the instance
print(obj.class_variable)

# Modifying the class variable using the class name
MyClass.class_variable = "Updated class variable"
print(MyClass.class_variable)
print(obj.class_variable)  # Note that instance variable remains the same

# Modifying the class variable using the instance
obj.class_variable = "Modified class variable through instance"
print(MyClass.class_variable)  # Note that class variable remains unchanged
print(obj.class_variable)

# Output:
# This is a class variable
# This is a class variable
# Updated class variable
# Updated class variable
# Updated class variable
# Modified class variable through instance
