Exclude dates based on a list from a pandas dataframe

Question

I have a dataframe with a pd.to_datetime column df, where the column day is: df['Date'].dt.day:

Day
01.01.2020
02.01.2020
...

And I have another dataframe with a pd.to_datetime column closeddays:

Closed
01.01.2020
31.01.2020

How can I exclude every row which is on the closed list, i tried:

df = df.loc[~df['Day'].isin([closeddays['Closed']])]

which leads to an error: TypeError: 'Series' objects are mutable, thus they cannot be hashed

How can i get the outcome:

Day
02.01.2020
...

Answer 1

你可以试试这个——

df = df[~(df['Date'].isin(closeddays['Closed'].dt.date.tolist()))]
