Hi James, I am using WinPython Spyder 3.6.

here i mean [with open('combine11.csv', 'wb') as f:] wb: writing binaries
if i am using "wb" so i m getting "TypeError: a bytes-like object is required, not 'str'"

if i am removing "b" and using only "w" so this error disappears and when i am writing data into txt/csv so it is just pasting what i am seeing in my console window. I mean i have 20045 time steps but i am getting 100.2...like that as previously mentioned. Not getting full time steps. It is like printscreen of my python console.

My question is how can i save multi-dimentional (3d: time series values, lat, long) data (xarrays) into csv. 

Thanks
