Whenever I try to open a .csv file with the python command fread = open(\'input.csv\', \'r\') it always opens the file with spaces between every single character.
fread = open(\'input.csv\', \'r\')
It did never ocurred to me, but as truppo said, it must be something wrong with the file.
Try to open the file in Excel/BrOffice Calc and Save As the file as Csv again.
If the problem persists, try a subset of the data: fist 10/last 10/intermediate 10 lines of the file.
