Write a Python script to merge two Python dictionaries. Sample Solution-1: Python Code: # Create the first dictionary 'd1' with key-value pairs. d1 = {'a': 100, 'b': 200} # Create the second dictionary 'd2' with key-value pairs. ...
to the next iterable. It will treat consecutive sequences as a single sequence.itertools.chain(*iterables)The list is also iterable, so we can use itertools.chain() to merge two dictionaries. The return type will beitertools.chain object.We can convert to a list using the list()constructor...

Python sort list of dictionaries When sorting dictionaries, we can choose the property by which the sorting is performed. sort_dict.py #!/usr/bin/python users = [ {'name': 'John Doe', 'date_of_birth': 1987}, {'name': 'Jane Doe', 'date_of_birth': 1996}, ...
In this method, the dictionary to be added will be passed as the argument to the update() method and the updated dictionary will have items of both the dictionaries. Let’s see how to merge the second dictionary into the first dictionary Example dict1 = {'Jessa': 70, 'Arul': 80, '...
