Thanks, Andreas, but it doesn't quite work.
This works for me (I manually changed all dates to 'day-month-year' for
testing):
a = loadtxt('test.csv',converters={2:strpdate2num('%d-%m-%Y')})
But when I define the same function in a separate function, as you
suggested:
def conv_date(s):
return strpdate2num('%d-%m-%Y')
and do
a = loadtxt('test.csv',converters={2:conv_date})
I get the non-descript error:
loadtxt(fname, dtype, comments, delimiter, converters, skiprows, usecols,
unpack, ndmin)
847 fh.close()
848
--> 849 X = np.array(X, dtype)
850 # Multicolumn data are returned with shape (1, N, M), i.e.
851 # (1, 1, M) for a single row - remove the singleton dimension
there
SystemError: error return without exception set
Any suggestions?
Thanks, Mark
