test_list = [
{‘data‘: 1, ‘no‘: 301},
{‘data‘: 2, ‘no‘: 401},
{‘data‘: 4, ‘no‘: 201},
{‘data‘: 6, ‘no‘: 101},
{‘data‘: 5, ‘no‘: 303}
]
new_list = list(test_list)
# print(new_list)
for match in test_list:
if match[‘no‘] > 300:
match[‘no‘] = ‘BF‘
else:
match[‘no‘] = ‘BR‘
# print(test_list)
new_list[1][‘data‘] = 7
new_list.pop()
print(test_list)
print(new_list)

原因：
dict()也同样
