can you append a dictionary to a list python code example

Example 1: Python dictionary append

# to add key-value pairs to a dictionary:

d1 = {
	"1" : 1,
	"2" : 2,
  	"3" : 3
} # Define the dictionary

d1["4"] = 4 # Add key-value pair "4" is key and 4 is value

print(d1) # will return updated dictionary

Example 2: python append value to dictionary list

import collections

a_dict = collections.defaultdict(list) # a dictionary key --> list (of any stuff)
a_dict["a"].append("hello")

print(a_dict)
>>> defaultdict(<class 'list'>, {'a': ['hello']})

a_dict["a"].append("kite")

print(a_dict)
>>> defaultdict(<class 'list'>, {'a': ['hello', 'kite']})
