Question

pd.Series(Confirmed_df["Country/Region"]).convert_objects(convert_numeric= True)

FutureWarning: convert_objects is deprecated. To re-infer data dtypes for object columns, use Series.infer_objects() For all other conversions use the data-type specific converters pd.to_datetime, pd.to_timedelta and pd.to_numeric. after removing the cwd from sys.path.

but it is still (object) I want to convert to int type.

Answer 1

IICU:

df=pd.DataFrame({'Country':['Antigua and Barbuda','Argentina','Kenya']})
codes,uniques=pd.factorize(df.Country)
codes

Obviously, to convert to column

df['x']=pd.Series(codes)
df
