Trying to find a nice and clean solution in python with currying

headline.py

#!/usr/local/bin/python3.6

def init_hr():
    number = 0
    def inner():
        nonlocal number
        number += 1
        print("============================================================================")
        print("============================== UEBUNG ", number, "===================================")
        print("============================================================================")
        print()
        print()
    return inner

hr = init_hr()
hr()
hr()
hr()

# Kind of decorator, although it changes the interface of the function

def call_with_sequence_of_numbers(func):
    number = 0
    def wrapper():
        nonlocal number
        number += 1
        func(number)
    return wrapper

@call_with_sequence_of_numbers
def print_headline(number):
    print("============================================================================")
    print("============================== UEBUNG ", number, "===================================")
    print("============================================================================")
    print()
    print()

print_headline()
print_headline()
print_headline()
