Me parece que debe colocar la palabra Bearer antes del token, dejo como lo hice yo.

1def get_products(token):
2   headers = {
3       'Content-Type': 'application/json',
4       'Accept': 'application/json',
5       'charset': 'utf-8',
6       'Authorization': f'Bearer {token}'
7   }
8
9   try:
10       response = requests.get('https://fakestoreapi.com/products', headers=headers)
11
12       if response.status_code == 200:
13           return response.json()
14       else:
15           raise Exception('Error al intentar consultar productos')
16
17   except requests.exceptions.RequestException as err:
18       print("Error: {}".format(err))
