Positional arguments of variable size

Let's practice positional arguments of variable size. Your task is to define the function sort_types(). It takes a variable number of positional arguments and checks if each argument is a number or a string. The checked item is inserted afterwards either in the nums or strings list. Eventually, the function returns a tuple containing these lists.

Use the Python's built-in isinstance() function to check if an object is of a certain type (e.g. isinstance(1, int) returns True) or one of the types (e.g. isinstance(5.65, (int, str)) returns False).

Types to use in this task are int, float, and str.

通过完成这段示例代码来试试这个练习。

# Define the function with an arbitrary number of arguments
def sort_types(____):
    nums, strings = [], []    
    for arg in args:
        # Check if 'arg' is a number and add it to 'nums'
        if ____:
            nums.____
        # Check if 'arg' is a string and add it to 'strings'
        elif ____:
            strings.____
    
    return (nums, strings)
            
print(sort_types(1.57, 'car', 'hat', 4, 5, 'tree', 0.89))
