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.
