dict.append 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: 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: 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 4: Python dictionary append

testing1={'one':1,'two':2}
''' update() is the method of dict() merges another dict into existing ones '''
''' it replaces the keys of exisiting ones with the the new ones '''
testing1.update({'two':3,'noice':69}) 
print(testing1) """ {'one':1,'two':3,'noice':69} """

Example 5: append dictionary python

>>> d1 = {1: 1, 2: 2}
>>> d2 = {2: 'ha!', 3: 3}
>>> d1.update(d2)
>>> d1
{1: 1, 2: 'ha!', 3: 3}

Example 6: python dictoinary add value

student_scores = {'Simon': 45  }
print(student_scores)
# {'Simon': 45}
student_scores['Sara'] = 63
print(student_scores)
# {'Simon': 45, 'Sara': 63}
