Task 3: Deal with missing hours - Wrong Solution

timestamp_start = "2020-01-01 00:00"
timestamp_end = "2020-12-31 23:00"

expected_timestamps = pandas.date_range(start=timestamp_start, end=timestamp_end, freq="H")

for timestamp in expected_timestamps:
    if not (weather_data[LABEL_DATETIME]] == timestamp).any():
        weather_data.append(pandas.Series(name=timestamp))`

The input weather_data[LABEL_DATETIME]] for the if not condition does not work. First of all the square bracket is closed twice.

If we have already used LABEL_DATETIME as an index value, we can no longer use it as a column name. Replacing weather_data[LABEL_DATETIME]] with weather_data.index does the trick.
