Print Statement Suppression

[jejjohnson]

Hi,

First of all, I really like this package. Thank you for making it easier for beginners to use regrid functions without all of the boilerplate stuff that's needed. Super useful.

I was wondering if there was a way to suppress the print statements of the regridding method? Perhaps we can add a verbose argument if such a way doesn't already exists?

Example

** Code snippet to reproduce **

reference_ds = gpp_data_low
method = 'nearest_s2d'

# initialize regridder
regridder = xe.Regridder(
    gpp_data_hi,       # DataArray to be converted
    gpp_data_low,      # reference DataArray
    method=method,
)

# regrid new dataset
gpp_new = regridder(gpp_data_hi.compute())

** Output **

Overwrite existing file: nearest_s2d_432x936_144x312.nc 
 You can set reuse_weights=True to save computing time.

Expected Behavior

Nothing unless prompted.

System information

Glad that you find xesmf useful!

One possible fix is to change print to warnings.warn, which can be disabled by warnings.filters.

Such printing will no longer exist with the new regridder save-load API #75, so the current sub-optimal API is probably not worth fixing...

Thank you for the response! I agree; since the API will change then it's probably not worth fixing.

Thank you again!

I found this as a neat temporary solution for suppressing print statements from regridder until the API changes go through.
