python append to list in dict code example

Example 1: python dictionary of lists append

# Creating an empty dictionary 
myDict = {} 
  
# Adding list as value 
myDict["key1"] = [1, 2] 
  
# creating a list 
lst = ['Geeks', 'For', 'Geeks'] 
  
# Adding this list as sublist in myDict 
myDict["key1"].append(lst) 

# Print Dictionary
print(myDict)

Example 2: 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 3: 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
