What's the best way to check for type in Python?
The built-in type() function is the most commonly used method for checking the type of an object in Python. For example, type(my_variable) will return the type of my_variable. Additionally, you can use the isinstance() function to check if an object is an instance of a particular class or a subclass thereof. For example, isinstance(my_variable, int) will return True if my_variable is an instance of the int class.
Here's an example of using the type() function:
x = 5
print(type(x)) # Output: <class 'int'>
y = "hello"
print(type(y)) # Output: <class 'str'>
You can also use isinstance() to check if an object is an instance of a particular class or a subclass thereof. For example,
class A:
pass
class B(A):
pass
x = A()
y = B()
print(isinstance(x, A)) # Output: True
print(isinstance(y, A)) # Output: True
Here x is an instance of class A and y is an instance of class B, which is a subclass of A, so both would return True when we check if they are instances of A.
