how to append to a dictionary in python code example
Example 1: 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++'}
Example 2: add new keys to a dictionary python
d = {'key':'value'}
print(d)
# {'key': 'value'}
d['mynewkey'] = 'mynewvalue'
print(d)
# {'mynewkey': 'mynewvalue', 'key': 'value'}
Example 3: how to add an element in dictionary
thisdict = {
"brand": "Ford",
"model": "Mustang",
"year": 1964
}
thisdict["color"] = "red"
print(thisdict)
Example 4: python3 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)
print(dict_1)
#Output = {"1":"a", "2":"b", "3":"c", "4":"d", "5":"e", "6":"f"}
Example 5: how to append to a dictionary in python
d = {'a': 1, 'b': 2}
print(d)
d['a'] = 100 # existing key, so overwrite
d['c'] = 3 # new key, so add
d['d'] = 4
print(d)
Example 6: 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
