Sind Werte aus Dataframe1 in Dataframe 2 enthalten?

[explodingkitten]

Hello,

I have two dataframes and would like to know if values from dataframe1 are included in dataframe 2.

My dataframes look something like the following:

'Holidays_he = {'holiday': ['Whit Monday','Epiphany', 'summer vacation', 'summer vacation'],
'date': [datetime.date(2020-06-10),
datetime.date(2020-06-20),
datetime.date(2020-07-01),
datetime.date(2020-07-02)]}

Holidays_he_df = pd.DataFrame(Holidays)

Flights = {'route': ['SXF-STN','SXF-STN','STNSXF','STNSXF'],
'date': [datetime.date(2020-06-11),
datetime.date(2020-06-20),
datetime.date(2020-08-01),
datetime.date(2020-07-02)]}

Flights _df = pd.DataFrame(Flights )

I would now like to create a new column in Flights_df that will output to me in 0's and 1's whether or not there were holidays on the day of the flight.

Thanks in advance for your help.
