General information
RPNPy is a Python module which can read and write records of RPN files. It contains wrappers for librmn’s main fstd98 and convip C functions along with helper functions.
You can get the official description by clicking on the following link: RPNPy Reference
Note: The RPN functions read and write only one record at the time, not the whole file at once like the NetCDF functions. You need to loop over all the records you want to read or write.
To get access to this module in Python you have to acquire it before opening Python. For example for Python3 with
...
In your Python script you can then import the module with, for example:
| Volet |
|---|
| import rpnpy.librmn.all as rmn # Module to read RPN files |

List of main functions
Basic RPN functions
newdate(imode, idate1, idate2=0)
Convert date format between: printable, CMC date-time stamp, true date
incdatr(idate, nhours)
Increase idate by nhours
difdatr(idate1, idate2)
Compute the diffence between dates in hours (nhours = idate1 - idate2)
convertIp(mode, v, k=0)
Codage/Decodage level (P, kind <-> IP pour IP1, IP2, IP3)
Main fst-functions
fstopt(optName, optValue, setOget=0)
Set or print FST option. Use to suppress excessive "talking" of the following fst-functions.
