Hello,
I'm trying to read a time series of stream discharge using ts.genfromtxt.
The file looks like:
#agency_cd site_no datetime 02_00060_00003 02_00060_00003_cd
#5s 15s 16d 14n 10s
agency station 1940-07-01 1700 A
agency station 1940-07-02 350 A
I'm trying to read in the third 'date' column and the 4th 'data' column
using:
dateconverter = lambda y:
datetime.date(year=int(y.split('-')[0]),month=int(y.split('-')[1]),day=int(y.split('-')[2]))
flowts = ts.tsfromtxt('file', comments='#',datecols=2,
usecols=(2,3),dateconverter=dateconverter,freq='D')
This is returning an error
Line #25309 (got 3 columns instead of 2).
I'm fairly new with python and I'm hoping this will be a quick fix for the
experienced users here. I appreciate
any help I can get on this.
Thanks,
Solomon
