How would I change this to work with numpy: (Would it be more feasible for storing big files? 300-30,000 records) <br> for row in reader:<br> self.buffer.append(row)<br> s,a=[],{}<br> <br>
for j in range(len(self.buffer[0])):<br> a[self.buffer[0][j]]=row[j]<br> self.bufferp.append(a)<br> i+=1<br> self.total = i-1<br>
<br>Instead of doing self.buffer.append(row)<br><br>would I initialize numpy like this: self.buffer=numpy.array() and then in the loop do:<br>self.buffer.append(row) ? How do I achieve the same for lower code, where it appends to a dict with header of each column? Thank you.<br>

I might as well add a UnicodeReader and UnicodeWriter and support for passing delimiter in from other classes. At the same time. Anyone have a good csv class I can pick thru? I'm planning on posting my mysql adn curl classes that I use in my projects I just want to make them better and have less error.<div>

<div class="gmail_quote">It's main concern is to grab the file into the buffer for use in other classes. The self.soc.me_him is just so I know when its ENTERING or EXITING in that function when I run it in terminal. It's prints it in color. My main concern right now is to add error handling. I'm still learning how to use assert and yield, but I got try,except down pat. All this class does is grabs the file either from http or local storage into a buffer and I use that in other classes. I want to add support for creating creating csv as well. I read the doc on csv and will try some things out soon. Thanks for helping me.<div>

I know it's messy with all those self.soc.* functions, but it works in one of my current project. I just want to make it more pythonic I also want to add capability for makeing csv file if I give it input like:<br>
1234,something nice, hey this is something nice<br>
2468,something else, something else<br>

reader = csv.reader(file(filename, "rb"))<br>
try:<br>
for row in reader:<br>
self.buffer.append(row)<br>

Do you know that there is a csv module in the standard library already?<br>

I'd say he already knows, he even used it in the code.<br>

To Alex G.: I didn't understand what's the purpose of this class. Probably you want to do too much things in the same place; looks like it has multiple concerns, and that's not a good idea usually.<br>
