dictionary in python does not support append operation
dict_append = {"1" : "Python", "2" : "Java"}
dict_append.update({"3":"C++"}) # append doesn't supported in dict
# instead , use update in dict
print(dict_append)
# output : {'1': 'Python', '2': 'Java', '3': 'C++'}add new keys to a dictionary python
d = {'key':'value'}
print(d)
# {'key': 'value'}
d['mynewkey'] = 'mynewvalue'
print(d)
# {'mynewkey': 'mynewvalue', 'key': 'value'}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 dictionarypython3 add dictionary to dictionary
dict_1 = {"1":"a", "2":"b", "3":"c"}
dict_2 = {"4":"d", "5":"e", "6":"f"}
dict_1.update(dict_2)
