Split strings in tuples into columns, in Pandas

Question

I have the following DataFrame, where Track ID is the row index. How can I split the string in the stats column into 5 columns of numb

Answer 1

If you have a sequence of tuples and not strings, and you want them as DataFrame columns, this is the simplest approach:

df = pd.concat([df['Track ID'],pd.DataFrame(df['stats'].values.tolist())], axis=1)

If it is actually strings, you can first convert it to lists like so, then apply the above operation:

dfpart = pd.DataFrame(df['stats'].apply(lambda x: x.strip('()').split(', ')).values.tolist()).astype(float)
df = pd.concat([df['Track ID'], dfpart], axis=1)
