Python pandas fillna()

I have a large dataframe with the following values:

Name  A  B  C  D  E  F  G # Coulmns
Matt  1  n  n  n  5  n  5  # rows
Jake  n  n  2  n  3  n  n
Paul  2  n  3  n  n  8  n

I just want to fill NA values ​​with previous values:

df.fillna(method='ffill')

This is the forward fill method which gives me the following output:

Name  A  B  C  D  E  F  G # Coulmns
Matt  1  1  1  1  5  5  5  # rows
Jake  n  n  2  2  3  3  3
Paul  2  2  3  3  3  8  8

The problem is that I don't want it to go to the end and stop if there are no more values ​​behind. See line 2, Jake, it must stop at E because it doesn't have any value in the last column. Desired output:

Name  A  B  C  D  E  F  G # Coulmns
Matt  1  1  1  1  5  5  5  # rows
Jake  n  n  2  2  3  n  n
Paul  2  2  3  3  8  8  n

Is there anyway to do this with pandas?

code:

 for i in range(len(df)):
    df.loc[i][1:].fillna(method='ffill',inplace=True)
