csv dictreader

[brnstrmrs]

I am trying to use the dictionary reader to import the data from a csv
file and create a dictnary from it but just can't seem to figure it
out.

Here is my code:

>>>import csv
>>>reader = csv.DictReader( open('table.csv '))
>>>for row in reader:
>>>print row

my csv files looks like this:

Bytecode,Elemen t
\x00\x00,0000
\x01\x00,0001
.....
\x09\x00,0009

My output shows:
{'Bytecode': '\\x00\\x00', 'Element': '0000'}
{'Bytecode': '\\x01\\x00', 'Element': '0001'}
....
{'Bytecode': '\\x09\\x00', 'Element': '0009'}

1. how can I get access to this directory
2. why does the values come with two backslashs infront of the "x"

What do you mean? You can get each element in the dict by doing this:

for row in reader:
print row['Bytecode']
print row['Element']

2. why does the values come with two backslashs infront of the "x"

The double back slash is for escaping purposes, I think. If you print
this: '\\x09\\x00'
you'll get this: \x09\x00

Thanks. It works for the Bytecode but when I do print row['Element']
I get a error message print row['Element'] KeyError: 'Element'

That's weird. Since I only had your output, I did the following:

<code>

reader = [ {'Bytecode': '\\x00\\x00', 'Element': '0000'},{'Bytec ode':
'\\x01\\x00', 'Element': '0001'} ]

for x in reader:
print x['Element']
print x['Bytecode']


0000
\x00\x00
0001
\x01\x00

</code>

I must be missing something...

Re: csv dictreader

It looks like the backslash is messing the whole thing up so I
reposted to try to find out how to get over the backslash hump.

I sure hope your data is more complex than that... otherwise it's a
