Pandas Very Simple Percent of total size from Group by

Question

I\'m having trouble for a seemingly incredibly easy operation. What is the most succint way to just get a percent of total from a group by operation such as df.groupby

Answer 1

I don't know if I'm missing something, but looks like you could do something like this:

df.groupby('A').size() * 100 / len(df)

or

df.groupby('A').size() * 100 / df.shape[0]
