Python: Remove duplicate dictionary from a given list

Python List: Exercise - 113 with Solution

Write a Python program to remove duplicate dictionary from a given list.

Sample Solution:

Python Code:

def remove_duplicate_dictionary(list_color):
    result = [dict(e) for e in {tuple(d.items()) for d in list_color}]
    return result

list_color = [{'Green': '#008000'}, {'Black': '#000000'}, {'Blue': '#0000FF'}, {'Green': '#008000'}]
print ("Original list with duplicate dictionary:")
print(list_color)
print("\nAfter removing duplicate dictionary of the said list:")
print(remove_duplicate_dictionary(list_color))

Sample Output:

Original list with duplicate dictionary:
[{'Green': '#008000'}, {'Black': '#000000'}, {'Blue': '#0000FF'}, {'Green': '#008000'}]

After removing duplicate dictionary of the said list:
[{'Black': '#000000'}, {'Blue': '#0000FF'}, {'Green': '#008000'}]

Python: Tips of the Day

Floor Division:

When we speak of division we normally mean (/) float division operator, this will give a precise result in float format with decimals.

For a rounded integer result there is (//) floor division operator in Python. Floor division will only give integer results that are round numbers.

print(1000 // 300)
print(1000 / 300)

Output:

3
