for m in v:
    if v[m]=="":
        v.pop(m)

This Python code checks the dictionary named v and if the name of the key has a value of that is empty, it is removed.

Did you mean dictionaries with two or more empty fields?

count=0
for p in s:
    if s[p]=="":
        count+=1
if count>1:
    del s
count=0
for p in e:
    if e[p]=="":
        count+=1
if count>1:
    del e
count=0
for p in t:
    if t[p]=="":
        count+=1
if count>1:
    del t
count=0
for p in o:
    if o[p]=="":
        count+=1
if count>1:
    del o
#The dictionary o is deleted if it has more than one empty field i.e. more than one key with empty value.
