Każde wywołanie metody DataFrame.replace z parametrem inplace=True loguje nastepujący warning:

FutureWarning: A value is trying to be set on a copy of a DataFrame or Series through chained assignment using an inplace method.
The behavior will change in pandas 3.0. This inplace method will never work because the intermediate object on which we are setting values always behaves as a copy.

For example, when doing 'df[col].method(value, inplace=True)', try using 'df.method({col: value}, inplace=True)' or df[col] = df[col].method(value) instead, to perform the operation inplace on the original object.

Poprawiłem wszystkie linijki zgodnie z sugestią z warninga, dodatkowo replace można wołać jedno po drugim.

Teraz też zauważyłem że wszystkie dane mają spację na początku, przez co replace nic nie robił bo nie mógł nic zmatchować
