update nested dictionary python using for loop code example
Example 1: iterate through nested dictionary python
d = {'dict1': {'foo': 1, 'bar': 2}, 'dict2': {'baz': 3, 'quux': 4}}
for k1,v1 in d.iteritems(): # the basic way
temp = ""
temp+=k1
for k2,v2 in v1.iteritems():
temp = temp+" "+str(k2)+" "+str(v2)
print temp
Example 2: update nested dictionary python
import collections.abc
def update(d, u):
for k, v in u.items():
if isinstance(v, collections.abc.Mapping):
d[k] = update(d.get(k, {}), v)
else:
d[k] = v
return d
