Python callable
Python callable() builtin function checks if given object is callable or not. callable() returns True if the argument passed to it is callable, else it returns false.
In this tutorial, we will learn about the syntax of Python callable() function, and learn how to use this function with the help of examples.
Syntax
The syntax of callable() function is
callable(object)
where
| Parameter | Required/Optional | Description |
|---|---|---|
| object | Required | The object which has to be checked if callable or not. |
Returns
The function returns boolean value.
Examples
1 callableFunction
In this example, we will define a function myFunc and pass this function as argument to callable() builtin function. Since a function is callable, callable(myFunc) should return True.
Python Program
def myFunc():
print('hello wolrd!')
result = callable(myFunc)
print(f'Return Value: {result}')
Output
Return Value: True
2 callablevariable
In this example, we will give an integer value in variable x as argument to callable() function. Since, integer value is not callable, callable(x) should return False.
Python Program
x = 10
result = callable(x)
print(f'Return Value: {result}')
Output
Return Value: False
3 callableBuiltin Function
In this example, we will pass a builtin function, say list, as argument to callable() function. Since a builtin function is callable, callable(list) should return True.
Python Program
result = callable(list)
print(f'Return Value: {result}')
Output
Return Value: True
Conclusion
In this Python Tutorial, we have learnt the syntax of Python callable() builtin function, and also learned how to use this function, with the help of Python example programs.
