Python: List of dictionary stores only last appended value in every iteration

Question

I have this list of dictionary:

MylistOfdict = [{\'Word\': \'surveillance\',
  \'Word No\': 1},
 {\'Word\': \'equivocal\',
  \'Word No\': 2}]

Answer 1

Use deepcopy. What's happening is that your append call is just appending a reference to the original object.

from copy import deepcopy

my_list_of_dict = [{'Word': 'surveillance',
                    'Word No': 1},
                   {'Word': 'equivocal',
                    'Word No': 2}]
word_db2 = []

key = 1
for i in my_list_of_dict:
    for j in range(1, 4):
        i['Card Type'] = 'Type ' + str(j)
        i['Card Key'] = key
        print(i)
        word_db2.append(deepcopy(i))
        key += 1


for i in word_db2:
    print(i)
