20 days prior to 1st of October, 2018 ("Pandas")

Question

There is a case am working since 2 days to solve the following issue:

end_Date = "1st October, 2018"
end_Date = pd.to_datetime(end_Date)
start_Date = end_Date - pd.Timedelta(days = 20)

df360[(df360.claim_date <= str(end_Date)) & (df360.claim_date >= str(start_Date))['claim_amount'].sum()

while I do this: I get the following error

File "<ipython-input-44-1a6629fd9584>", line 1 df360[(df360.claim_date <= str(end_Date)) & (df360.claim_date >= str(start_Date))['claim_amount'].sum() ^ SyntaxError: unexpected EOF while parsing

Answer 1

Fix your code with .loc

df360.claim_date = pd.to_datetime(df360.claim_date)
df360.loc[(df360.claim_date <= end_Date) & (df360.claim_date >= start_Date),'claim_amount'].sum()

Answer 2

I've did it in jupyter notebook:

end_Date = "1st October, 2018"
end_Date = pd.to_datetime(end_Date)
start_Date = end_Date - pd.Timedelta(days = 20)

Then:

df360['claim_amount'].dtypes

See whether you get this as output:

dtype('float64')

and not:

dtype('o')

then paste this code:

df360[(df360.claim_date <= end_Date) & (df360.claim_date >= start_Date)]['claim_amount'].sum()

i get the output successfully! & thanks for the help!
