In Python, you can check the data type of a variable using the built-in function type().

Example:

x = 42
print(type(x))  # Output: <class 'int'>

y = "Hello"
print(type(y))  # Output: <class 'str'>

z = [1, 2, 3]
print(type(z))  # Output: <class 'list'>

Additional tips:

  • To check if a variable is of a specific type, use isinstance():
if isinstance(x, int):
    print("x is an integer")
  • type() returns the exact type, while isinstance() supports inheritance (useful for checking subclasses).
