Python dictionary is a collection key value pair, unlike like python list, values in dictionary are stored and accessed using key, where in list we will use index.
In list to append a value, we can use a inbuild list method append to add a value to list.
l = [1,2,3,4,5]
l.append(6)
print(l)
# Output:
1, 2, 3, 4, 5, 6
Append a value to dictionary
To add a new value to dictionary, simply use the assignment operator, if the key value is not in dict, python will add a new entry. If the key is already exist in dict then it will update the value
d = { "a": 1, "b": 2 }
d["c"] = 3
print(d)
# Output
{ "a": 1, "b": 2, "c": 3 }
d["c"] = 20
print(d)
# Output
{ "a": 1, "b": 20, "c": 3 }
