KeyError: 1L in hash table

[Jayakumar Bellie]

I have to create a has table like

{ '1':'data1', '2':'data2', '10':'data3', '50':'data4' }

I get the data from the database, here is the code where I format the data

1        dataTypeList = {}

2        for row in result:

3           dataTypeList[row.number_indicator] = dataTypeList[row.data]

I get KeyError: 1L error in line 3

It is a mistake made my me I dont know how did I miss it, very bad.

dataTypeList[row.number_indicator] = dataTypeList[row.data]

it should be 

dataTypeList[row.number_indicator] = row.data

[Niphlod]

how do you expect to run such code in a python environment ?
the first loop of that cycle tries to create a key within an empty dictionary with a value from an empty dictionary .... it's going to fail every time if row.data isn't in the dictionary yet.

Perhaps you meant to do:

    dataTypeList[row.number_indicator] = row.data
