TypeError while using positional argument in decorators

I am getting following error while performing a simple decorator code

"decorator_func() missing 1 required positional argument: 'original_func'"

Appreciate if someone points at the issue, thanks.

Here is the code:

def decorator_func(original_func):
    def wrapper_func(*args, **kwargs):
       return original_func(*args, **kwargs)

    return wrapper_func()

@decorator_func() #also tried without calling i.e. @decorater_func
def displayInfo_func(name, age):
        print('Display Info func ran with arguments ({}, {})'.format(name))

displayInfo_func

Thanks in advance.

The problem is while returning wrapper function you are calling it and that too without any arguments.

def decorator_func(original_func):
    def wrapper_func(*args, **kwargs):
       return original_func(*args, **kwargs)

    return wrapper_func #instead of wrapper_func()

@decorator_func() #also tried without calling i.e. @decorater_func
def displayInfo_func(name, age):
    print('Display Info func ran with arguments ({}, {})'.format(name))
