Given a Dictionary, the task is to write a python program to swap positions of dictionary items. The code given below takes two indices and swap values at those indices.
Input : test_dict = {‘Gfg’ : 4, ‘is’ : 1, ‘best’ : 8, ‘for’ : 10, ‘geeks’ : 9}, i, j = 1, 3 Attention geek! Strengthen your foundations with the Python Programming Foundation Course and learn the basics. To begin with, your interview preparations Enhance your Data Structures concepts with the Python DS Course. And to begin with your Machine Learning Journey, join the Machine Learning - Basic Level Course Output : {‘Gfg’: 4, ‘for’: 10, ‘best’: 8, ‘is’: 1, ‘geeks’: 9} Explanation : (for : 10) and (is : 1) swapped order. Input : test_dict = {‘Gfg’ : 4, ‘is’ : 1, ‘best’ : 8, ‘for’ : 10, ‘geeks’ : 9}, i, j = 2, 3 Output : {‘Gfg’: 4, ‘is’: 1, ‘for’: 10, ‘best’: 8, ‘geeks’: 9} Explanation : (for : 10) and (best : 8) swapped order.
Method : Using items() and dict()
This task is achieved in 3 steps:
Example:
# initializing dictionary test_dict = {'Gfg': 4, 'is': 1, 'best': 8, 'for': 10, 'geeks': 9} # printing original dictionary print("The original dictionary is : " + str(test_dict)) # initializing swap indices i, j = 1, 3 # conversion to tuples tups = list(test_dict.items()) # swapping by indices tups[i], tups[j] = tups[j], tups[i] # converting back res = dict(tups) # printing result print("The swapped dictionary : " + str(res))
Output:
The original dictionary is : {‘Gfg’: 4, ‘is’: 1, ‘best’: 8, ‘for’: 10, ‘geeks’: 9} The swapped dictionary : {‘Gfg’: 4, ‘for’: 10, ‘best’: 8, ‘is’: 1, ‘geeks’: 9}
