Reading data from a text file into a list

I'm trying to read some data from a text file I created into a list, but keep getting the "TypeError: 'str' object is not callable" error when i try to do this.

Here is the code

class Weather(): 
  """
  Weather Class 
  """
  def __init__(self,weather = ''): 
    self.weather= weather 
    
  def rome_weather(self, weather =''):
    """
    City temperature function 
    """
    #retrieving geocoding API to find longitude and latitude
    api = '66c622a1d43cb6e0010946bc5408b773'
    geo_url = f"http://api.openweathermap.org/geo/1.0/direct?q=Rome,IT&limit=2&appid={api}"
    request = urllib.request.urlopen(geo_url)
    result = json.loads(request.read())

    #defining longitude and latititude
    for value in result:
      for key in value:
        lon = value["lon"]
        lat = value["lat"]

    #retrieving current weather API
    weather_url = f"https://api.openweathermap.org/data/2.5/weather?lat={lat}&lon={lon}&appid={api}"
    request2 = urllib.request.urlopen(weather_url)
    result2 = json.loads(request2.read())

    #temperature variable
    weather = result2['main']['temp'] - 273.15
    weather = round(weather,2)
    return f"{weather}\n"
    
weather= Weather()
for value in range(200):
  with open ('romeweather.txt','a') as f:
    f.write(str(weather.rome_weather(weather)))

rome=[]
with open ('romeweather.txt','r') as f:
  for line in f:
    if len(rome) <= 200:
      rome.append(float(line()))

A class is made with a function that calls the temperature of Rome, from an API. This info is then stored in a text file "romeweather.text". I need to store 200 lines of the data from that file into a list. The list part isnt working for me because the data is in the form of floats ex.15.67 on each line. I keep running into this error:

Traceback (most recent call last):
  File "main.py", line 111, in <module>
    rome.append(float(line()))
TypeError: 'str' object is not callable

Please let me know how I can make it work.

As has been previously said (and read by the error) you're trying to call a string, which is not callable. Simply remove the brackets on 'line()' and it will solve your problem.

rome.append(float(line))

Line 111 should be as follows.

rome.append(float(line))

The problem was the () brackets that was causing python to try and call line when it was in fact a string.
