[ncl-talk] Wonder if there is any printVarSummary() equivalent function in pynio

[谢瑾博]

Sory for a little digging in this issue. The print() variables, as stated in this website, shows that the print summary can be done once a data is read in and has a reference f. I wonder if this can be used after I used an array that gets the variable and maybe another that process the data again once getting the variables from f? In the old ncl, printVarSummary can basically be used anywhere and any array, not restricted to a reference variable in f. Can this work for Nio?
yours,
Jinbo

Yes, print() works for variables too;  this is from the documentation


https://www.pyngl.ucar.edu/Nio.shtml
Print a summary of a variable in the file
print f.variables['varName']

Here is a sample print of the variable "elev":
Variable: elev
Type: float
Total Size: 259200 bytes
            64800 values
Number of Dimensions: 2
Dimensions and sizes:   [lat | 180] x [lon | 360]
Coordinates: 
            lat: [89.5..-89.5]
            lon: [0.5..359.5]
Number of Attributes: 3
         units :        meters
         long_name :    median topography
         _FillValue :   -99999

Hi Rick,
Does this work for variables inside the program? Because printVarSummary() tends to work anywhere in the program, and sometimes we may want to know the attributes after a certain processing.

Hi,


I believe if you just print() the variable you get back from Nio.open_file(), it behaves like printVarSummary()

Dear Users,
I wonder if there is any printVarSummary()  equivalent function in the pynio, this is a very handy function to print the attributes summary of the variables.

Jinbo
