97. Problem to remove duplicate dictionaries from the list.

by

In this Python list program, we will take a list containing dictionaries and remove duplicate dictionaries from the list with the help of the below-given steps.

Remove duplicate dictionaries from list:

Steps to solve the program
  1. Take a list containing dictionaries as input and create an empty dictionary.
  2. Use for loop to iterate over each dictionary from the given list.
  3. Add that list to the empty list if it is not in that list.
  4. Print the list to see the output.
				
					#Input list
list1 = [{'Hello': 5},{'student': 7},{'are': 3},{'learning': 8},
         {'Python': 6},{'Its': 3},{'Language': 8},{'are':3}]
list2 = []

for value in list1:
    if value not in list2:
        list2.append(value)

#Printing output
print(list2)

Output :

				
					[{'Hello': 5}, {'student': 7}, {'are': 3}, 
{'learning': 8}, {'Python': 6}, {'Its': 3}, {'Language': 8}]

Convert tuples in list to sublist:

Steps to solve the program
  1. Take a list containing tuples as input.
  2. Using for loop convert tuples in list to sublist.
