I have a dataframe like this:

Entry    Frequency
A        20
B        10
C        15

I want to create a third dataframe which is a cumulative frequency that is the summation of frequency counts of respective previous frequency column entries

Entry    Frequency   Cumulative Frequency
A        20            20
B        10            30
C        15            65

Any clue how to achieve this?

`df.Frequency.cumsum()`? – Dani Mesejo Oct 13 '19 at 19:39

`df['Cumulative Frequency'] = df['Frequency'].cumsum()` – Willem Van Onsem Oct 13 '19 at 19:39

Did you mean 65 or 45? – Dani Mesejo Oct 13 '19 at 19:44
