how to create a dictionary in a dictionary by appending 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: 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"}
