Python issubclass() Function
The issubclass() function in Python is used when we need to check whether a class is a sub-class of another class or not. For example:
class fresherearth: Name = "Sophia" Course = "EECS" Age = "20"class obOne(fresherearth): Name = fresherearth City = "Liverpool"if issubclass(obOne, fresherearth): print("'obOne' is a sub-class of 'fresherearth'") else: print("'obOne' is not a sub-class of 'fresherearth'")
Because obOne is created as a sub-class of fresherearth. Therefore the output will be:
'obOne' is a sub-class of 'fresherearth'
Python issubclass() Function Syntax
The syntax of issubclass() function in Python, is:
issubclass(class, classinfo)
where class is a class that has to be check whether it is a sub-class of classinfo or not. The classinfo refers to a class, types, or a tuple of classes and/or types.
Note: The function issubclass() returns True, if first argument (class) is a sub-class of second argument (classinfo). Otherwise returns False.
Python issubclass() Function Example
Here is an example of issubclass() function in Python:
class fresherearth: Name = "Sophia" Course = "EECS" Age = "20" class obOne(fresherearth): Name = fresherearth City = "Liverpool" print(issubclass(obOne, fresherearth)) print(issubclass(fresherearth, obOne)) print(issubclass(obOne, list)) print(issubclass(obOne, (list, fresherearth)))
The output will be:
True False False True
