How to change page in confluence using Python?

Question

Python

Good afternoon!
I can't figure out how to change the page in the confluence api.

I can get the page code itself using the get method:

def get_page_info(Link, login, password):
    #Берем "Суп" страницы:
    r = requests.get(str(Link), auth=HTTPBasicAuth(str(login), str(password)),verify=False)
    return r

I'm trying to run everything and use the put method to change the content:

def write_data():
    headers = {
        'Content-Type': 'application',
    }
    info = get_page_info('https://confluence........ru/pages/viewpage.action?pageId=635355', "111111","9999999")
    date = {"version": {"number": 2},
            "title": "КБ_9999 - Global Site",
            "type": "page",
            "body": {"storage": {"value": "<p>TESTTT.</p>",
            "representation": "storage"}}}
    response = requests.put('https://confluence.........ru/pages/viewpage.action?pageId=613355',headers=headers ,data=json.dumps(date), auth=HTTPBasicAuth(".....", '.....'),verify=False)
    result = get_page_info('https://confluence........ru/pages/viewpage.action?pageId=613655', "99999,"99999")
    print('1',result)
    

    
write_data()

(logins and passwords indicated random for the question)

I get a constant Response [200], but no changes happen to the page!
Perhaps I did not specify the values ​​​​in the date dictionary correctly?
Can you please explain why headers are needed and where do I get the values ​​for the date dictionary?
I took this code as an example from the Internet, I did not fully understand how it works
