how to add in key:value into empy dict with values be more than 1 items

Question

i need to take the user input from the text boxes and put it into my dict. my code is this but i seem to get keyerror.,

my_Dict = {}
v = self._etyV.get() # vehicle number 
n = self._etyN.get() # time in 
in, out, charge = m_Dict

this is to append into my_Dict with v as the key and in as value. but since time out and charge is not recorded yet it will just take as None.

my_Dict[v] = {in, None, None} 

Answer 1

I believe the answer you are looking for is

my_Dict.update({v : [time_in, None, None]})

Also for future reference the word in is a reserved keyword in python, not sure if you were aware.
