append in dict code example
Example 1: 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 2: 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 3: 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 4: append to dictionary python
# Append to Dictionary in Python
# Let's say we had the following dictionary:
languages = {'#1': "Python", "#2": "Javascript", "#3": "HTML"}
# There are two ways to add a key-and-value set to this dictionary
# Number 1: By .update() method
languages.update({"#4": "C#"}) # Adds a #4 key-and-value set
#--------------------------------------------
# Number 2: The define-key method
# This is the easier one
languages['#4'] = 'C#'
# ^^ Just updates a key of #4 to C#, or adds it in this case
Example 5: python dict append value
default_data = {'item1': 1,
'item2': 2,
}
default_data.update({'item3': 3})
# or
default_data['item3'] = 3
