WebThe isinstance () function returns True if the specified object is of the specified type, otherwise False. If the type parameter is a tuple, this function will return True if the object … WebIn this implementation, the function takes a parameter, lst that can be either a nested list of strings or a single string. If lst is a string, the function simply returns the length of the string. If lst is a list, the function first checks if the list is empty, in which case it returns 0.; If the list is not empty, the function recursively calls itself on the first element of the list and on ...

WebMar 23, 2024 · Let’s discuss certain ways how to check variable is a string.

By giving the second argument as “str”, we can check if the variable we pass is a string or not.

If a class method is called for a derived class, the derived class object is passed as the implied first argument. Class methods are different than C++ or Java static methods. The isinstance() built-in function is recommended for testing the type of an object, because it takes subclasses into account. So, if you're checking the type of a class object instead of a simple variable, and you need to take subclasses into account, then use isinstance() instead. bin52 wine and gourmet
