pygrametl CSVSource TypeError: init() takes at least 2 arguments (1 given)
I am trying to use pygrametl CSVSource as shown in the documentation
This is my code
import pygrametl
from pygrametl.datasources import CSVSource
src = CSVSource(csvfile=open('src.csv', 'r', 16384),
delimiter=',')
but I get the following error even though I use the exact code.
TypeError: init() takes at least 2 arguments (1 given)
How can I fix this?

From the documentation You mentioned, we can see that CSVSource is just reference to DictReader from csv module.
If we look at the source code of DictReader class (it's __init__ method, to be precise), we see this:
class DictReader:
def __init__(self, f, fieldnames=None, restkey=None, restval=None,
dialect="excel", *args, **kwds):
self._fieldnames = fieldnames # list of keys for the dict
self.restkey = restkey # key to catch long rows
self.restval = restval # default value for short rows
self.reader = reader(f, dialect, *args, **kwds)
self.dialect = dialect
self.line_num = 0
Since there is no keyword csvfile in the input arguments, this argument is passed to **kwds, meaning argument f is missing. I don't have this library installed, but I think that just passing open('src.csv', 'r', 16384) without csvfile= will fix this issue. Something like this:
import pygrametl
from pygrametl.datasources import CSVSource
src = CSVSource(open('src.csv', 'r', 16384), delimiter=',')
Update: Just installed pygrametl and tested without csvfile=, it works fine.
