[SOLVED!] How to convert frame.append() to pandas.concat()?

FutureWarning: The frame.append method is deprecated and will be removed from pandas in a future version. Use pandas.concat instead.

I was using frame.append method to add rows to a dataframe, yet it is deprecated and going to be removed from pandas.

So, in this article, I will tell you how to convert DataFrame.append() to pandas.concat(). It’s easy.

This is my original code with append method. With this code, I was appending a dataframe to b dataframe.

b = b.append(a)

So, this is how we achieve the same using pandas.concat:

b = pd.concat([b, a], axis=0)

This is quite easy. axis=0 means that the dataframes are going to be concatenated vertically.
