Dear all, I have files which contain lines like this:
30516F5 Sep 1985 1-Day Rain Trace 0.2 3.2 Trace 0.0 0.0 0.0 0.0 0.2 0.0 Trace 29.2 0.0 0.0 0.0 0.0 1.8 30516F5 Sep 1985 1-Day Snow Trace 0.0 0.0 0.0 14.8 10.1 Trace 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 Trace Trace 0.0 30516F5 Sep 1985 1-Day Pcpn. Trace 0.2 3.2 Trace 18.9 9.8 Trace 0.0 0.2 0.0 Trace 29.2 0.0 0.0 0.0 Trace 1.8 0.0 30516F5 May 1986 Max. Temp. Misg Misg Misg Misg Misg Misg 9.0 8.0 8.0 0.0 6.0 1.0 1.0 -3.0 3. 30516F5 May 1986 Min. Temp. Misg Misg Misg Misg Misg Misg Misg -1.0 -2.0 -6.0 -5.0 -5.0 -3.0 -7.0 -6.0 -5.0 -3.0 different columns were separated by blank spaces. with the first column as sitename, second as month name, then year, then variable name and data. I want to read them line by line into a list, and then connect all the numerical data within one year into a list, and then combining different year data into one masked ndarray, in this process, I check the flags (Trace, Misg, etc.) and replace them as unique values (or missing values). and then begin to analyse the data. each file contains only one site, it can be big or small depending on the number of years. I don't know what's the good way to do this job. what I am thinking is to read one file line by line, and then divide this line by blank space, and replace special flag. but during this process, I need to do type conversion. any suggestion would be appreciated.
