I did not find a solution to my problem so I try to post something about it. If there is an answer somewhere that I did not find I am sorry.

Well, I am using Python 3.10 and Spyder.
I want to work with a GRIB file and I have some difficulties with one of its parameter.

Here is my code :

GRIB_File_Path = r"/Path to my GRIB file/GRIB file name.grb"
    
gribfile = pygrib.open(GRIB_File_Path)
for grb in gribfile:
    print(grb)type here

The output is :

I want to access to the parameter 180, so my code is :

180_Parameter  = gribfile.select(name='180')[0]

The output is :

Parameter = gribfile.select(name='180')[0]

  File src/pygrib/_pygrib.pyx:575 in pygrib._pygrib.open.select

ValueError: no matches found

So I tried :

Parameter_Name = gribfile[90].parameterName
print(Parameter_Name)

The output is :

180

So I do not understand what I am doing wrong. If someone has an idea I would be happy to listen !
