import requests
from urllib.parse import urlencode

client_id = '***'
client_secret = '***'

# auth
data = {
	'client_id': client_id,
	'client_secret': client_secret,
	'grant_type': 'client_credentials',
	'scope': 'channel:manage:broadcast'
}

response = requests.post('https://id.twitch.tv/oauth2/token', data=data).json()

print(response)

token = response['access_token']
headers = {
	'Client-Id': client_id,
	'Authorization': 'Bearer ' + token,
}

# get broadcaster id
data = {
	'login': ['Flexlolo']
}

url = 'https://api.twitch.tv/helix/users?' + urlencode(data, doseq=True)
response = requests.get(url, headers=headers).json()

print(response)

broadcaster_id = response['data'][0]


# change title
data = {
	'broadcaster_id': broadcaster_id,
	'title': 'NEW TITLE STRING'
}

url = 'https://api.twitch.tv/helix/channels?' + urlencode(data, doseq=True)
response = requests.patch(url, headers=headers).json()

print(response)

and the output looks like this:
