calc_cam_climo logic needs help about adf HOT 2 CLOSED

For the record, @brianpm suggests that the get_info functions return boolean values.

from adf.

I didn't fix the problem, but I have a hypothesis for what is happening.

In adf_diag.py in create_climo is where that logic lives:

if self.get_cam_info('calc_cam_climo') or \
           self.get_baseline_info('calc_cam_climo'):

The get_cam_info method is in adf_info.py, but it doesn't do anything except:

return self.read_config_var(...)

The read_config_var method is in adf_config.py.

I'm pretty sure that what is happening is that read_config_var is working as intended like this

var = var_dict[varname]
return copy.deepcopy(var)

BUT that is a list: [False], and a list that is not empty evaluates as true:

if [False]:
    print("That's a problem")
