Key must not contain . error in pymongo

Question

I am trying to get the output of serverStatus command via pymongo and then insert it into a mongodb collection. Here is the dictionary

{u\'metrics\': {u\'getLa

Answer 1

In the 14th line:

u'.': {u'timeAcquiringMicros': {u'R': 218733L, u'W': 30803L}, u'timeLockedMicros': {u'R': 311478L, u'W': 145679L}}}   

For future safety, iterate through the keys, replace '.'s with '_' or something, and then perform a write.
