SettingwithCopyWarning

[Salocinz]

Hey,

I have tried to compile your code but there is the following error:

C:/Users/admin/Desktop/test/unbenannt4_alt.py:252: SettingWithCopyWarning:
A value is trying to be set on a copy of a slice from a DataFrame

See the caveats in the documentation: http://pandas.pydata.org/pandas-docs/stable/user_guide/indexing.html#returning-a-view-versus-a-copy
order['Tax Percentage'][order['Journey Type'] == 'Domestic'] = 0
C:/Users/admin/Desktop/test/unbenannt4_alt.py:63: SettingWithCopyWarning:

route['Warehouse Cost'][route['Warehouse Cost'].isnull()] = bigM
C:/Users/admin/Desktop/test/unbenannt4_alt.py:268: SettingWithCopyWarning:

See the caveats in the documentation: http://pandas.pydata.org/pandas-docs/stable/user_guide/indexing.html#returning-a-view-versus-a-copy
m.set_param(route, order)

Can you help me solve this?

Thanks a lot in advance!

Rewrite the line as:

order.loc[order.JourneyType == 'Domestic', 'TaxPercentage'] = 0

I hope that works!!

AttributeError: 'DataFrame' object has no attribute 'JourneyType'
After making those changes this is the error
