python - How do I change values in a dictionary in one key? -


for example, have key = name. within name, there's birthday, age, , phone number. change birthday keep rest. , i'm trying use existing file have names already.

so if want use tuple key syntax 

d[(name, phonenumber)] = birthday

as far using values in pre-existing file need open method.

file = open("filename.csv",r) # assuming have file of comma separated values  text = file.read()            .split("\n") peps = [p.split(",") p in text] dictionary = {} p in peps:     d[(p[column of name] , p[col# phone number)]]=p[#bday]

roughly. there several types of collections in python, {}, [], (), hash , set. recommend read on each here
