ENH: Total (that is: sum or "margins") for value_counts()

Feature Type

• Adding new functionality to pandas

• Changing existing functionality in pandas

• Removing existing functionality in pandas

Problem Description

The function "pd.crosstab" shows the count values for all the combinations. As an add-on you can choose "dropna" and "margins". The function "value_counts" does almost the same for a single series, but does not offer to show the total amount ("margins").

Feature Description

Add a new feature called "margin" (or "total") to value_counts, which –in addition– returns the total of all listed value counts (much like "margins" for the pd.crosstab function.

Alternative Solutions

"margins" in pd.crosstab

or

print(df.colA.shape[0]) df.colA.value_counts()
