I have a bit of code that runs through a dictionary and outputs the values from it in a CSV format. Strangely I'm getting a couple of blank lines where all the output of all of the dictionary entries is blank.

Right now I have a CSV file mapping the old and new account numbers with around 30K records. I read this in and store it as dict and when writing the new file grab the new account from the dict by key. My question i...
I've been trying to find a good and flexible way to parse CSV files in Python but none of the standard options seem to fit the bill. I am tempted to write my own but I think that some combination of what exists in numpy/scipy and the csv module can do what I need, and so I don't want to reinvent the wheel. I'd like the standard feature...
the following function parses a CSV file into a list of dictionaries, where each element in the list is a dictionary where the values are indexed by the header of the file (assumed to be the first line.) this function is very very slow, taking ~6 seconds for a file that's relatively small (less than 30,000 lines.) how can I speed it up...

Hi, I have multiple CSV files which I need to parse in a loop to gather information. The problem is that while they are the same format, some are delimited by '\t' and others by ','.

Using FileHelpers, I decorated a class with [DelimitedRecord(",")] and was going to output an enumeration of objects of that type as CSV. But, it didn't work because my class inherits from ActiveRecordLinqBase<T>, which caused some problems. So, I was wondering if I could just select an enumeration of anonymous types and somehow have f...
