Pandas: split column of lists of unequal length into multiple columns

Question

I have a Pandas dataframe that looks like the below:

                   codes
1                  [71020]
2                  [77085]
3                  [36415         


        

Answer 1

Another solution:

In [95]: df.codes.apply(pd.Series).add_prefix('code_')
Out[95]:
    code_0   code_1   code_2
1  71020.0      NaN      NaN
2  77085.0      NaN      NaN
3  36415.0      NaN      NaN
4  99213.0  99287.0      NaN
5  99233.0  99233.0  99233.0
