dictionary .append 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 to dictionary

dict = {1 : 'one', 2 : 'two'}
# Print out the dict
print(dict)
# Add something to it
dict[3] = 'three'
# Print it out to see it has changed
print(dict)

Example 3: python dict append

default_data = {'item1': 1,
                'item2': 2,
          	    }

default_data.update({'item3': 3})
# or
default_data['item3'] = 3

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
