Remove Duplicate Items From a Dictionary in Python and Keep The Order
The following Python program will remove the two duplicate records for {'APPLE': 20, 'MANGO': 30} entries from the list of directories.
def dedupe(items, key=None): seen = set() for item in items: val = item if key is None else key(item) if val not in seen: yield item seen.add(val) if __name__ == '__main__': a = [ {'APPLE': 20, 'MANGO': 30}, {'APPLE': 10, 'MANGO': 40}, {'APPLE': 20, 'MANGO': 30}, {'APPLE': 20, 'MANGO': 30}, {'APPLE': 10, 'MANGO': 15} ] #print(a) print(list(dedupe(a, key=lambda a: (a['APPLE'],a['MANGO']))))
Output:
[{'APPLE': 20, 'MANGO': 30}, {'APPLE': 10, 'MANGO': 40}, {'APPLE': 10, 'MANGO': 15}] Process finished with exit code 0
