In Python, variables are used to store data values. You can create a variable by simply assigning a value to it using the = operator.
x = 5y = "John"print(x) # Output: 5print(y) # Output: JohnDynamic Typing
Python variables are dynamically typed, meaning you don't need to declare their type. You can change the type of a variable by assigning a new value of a different type.
x = 4 # x is of type intx = "Sally" # x is now of type strprint(x) # Output: SallyMultiple Assignments
You can assign values to multiple variables in a single line.
a, b, c = 1, 2, 3print(a, b, c) # Output: 1 2 3You can also assign the same value to multiple variables simultaneously.
a = b = c = 300print(a, b, c) # Output: 300 300 300Type Checking
You can check the type of a variable using the type() function.
x = 5y = "John"print(type(x)) # Output: <class 'int'>print(type(y)) # Output: <class 'str'>Naming Conventions
