Remove non zero values from dictionary of dictionary in python-CodePudding

I have a dictionary of dictionary as below how to remove non zero key,values from this

{'abcdef': {'1987': 0.0,
  '0544': 0.0,
   '0568': 0.0,
  '3000': 0.0,
  '7095': 0.0,
  '75609': 1.0,
  '56565': 2.0,
  '98656': 3.0,
  '756095': 0.0,
  '23432': 0.0},
  'fgrd': {'1987': 0.0,
  '0544': 0.0,
   '0568': 0.0,
  '3000': 0.0,
  '7095': 0.0,
  '75609': 1.0,
  '56565': 2.0,
  '98656': 3.0,
  '756095': 0.0,
  '23432': 0.0}

}

Tried below, {key:val for key, val in my_dict.items() if val.values() != 0.0}

and getting AttributeError: 'float' object has no attribute 'values',

Thanks

Try this:

dct = {'abcdef': {'1987': 0.0,
  '0544': 0.0,
   '0568': 0.0,
  '3000': 0.0,
  '7095': 0.0,
  '75609': 1.0,
  '56565': 2.0,
  '98656': 3.0,
  '756095': 0.0,
  '23432': 0.0},
  'fgrd': {'1987': 0.0,
  '0544': 0.0,
   '0568': 0.0,
  '3000': 0.0,
  '7095': 0.0,
  '75609': 1.0,
  '56565': 2.0,
  '98656': 3.0,
  '756095': 0.0,
  '23432': 0.0},
       
  'xyz':0.0, 
  
}

out = {}
for k,v in dct.items():
    if isinstance(v, dict):
        out[k] = {k2:v2 for k2,v2 in v.items() if v2==0}
    else:
        out[k] = v
print(out)

Output:

{'abcdef': {'1987': 0.0, '0544': 0.0, '0568': 0.0, '3000': 0.0, '7095': 0.0, '756095': 0.0, '23432': 0.0}, 
'fgrd': {'1987': 0.0, '0544': 0.0, '0568': 0.0, '3000': 0.0, '7095': 0.0, '756095': 0.0, '23432': 0.0}, 
'xyz': 0.0}

you have to iterate over the primary dictionary and than look for values in secondary dict here is an example:

val = {'abcdef': {'1987': 0.0,
  '0544': 0.0,
   '0568': 0.0,
  '3000': 0.0,
  '7095': 0.0,
  '75609': 1.0,
  '56565': 2.0,
  '98656': 3.0,
  '756095': 0.0,
  '23432': 0.0}}

for dict_k in val:
    for dicts in val.values():
        for k in dicts.copy():
            if dicts[k] != 0.0:
                dicts.pop(k)
print(val)
