CS50 DNA 帮助 - 如何比较两个词典

Question

有人可以解释为什么我的代码返回不匹配，因为我认为你可以用“==”比较两个字典？

 import csv
 import sys
 import copy

 def main():
 # TODO: Check for command-line usage
 if len(sys.argv) != 3:
    sys.exit(1)
 # TODO: Read database file into a variable
 database = []
 key = []
 database_file = sys.argv[1]
 d = open(database_file, "r")
 reader = csv.DictReader(d)
 for name in reader:
     database.append(name)
 copy_database = copy.deepcopy(database)
 for i in range(len(copy_database)):
     del copy_database[i]["name"]
 for i in range(len(copy_database)):
     for k in copy_database[i]:
         key.append(k)
 remove_dup = list(set(key))

 # TODO: Read DNA sequence file into a variable
 sequence_file = sys.argv[2]
 s = open(sequence_file, "r")
 sequence = s.read()
 # TODO: Find longest match of each STR in DNA sequence
 match = {}
 for i in range(len(remove_dup)):
     match[remove_dup[i]] = longest_match(sequence,remove_dup[i])

 # TODO: Check database for matching profiles
 for i in range(len(database)):
     if match == copy_database[i]:
        print(database[i]["name"])
 print("No Match")

我可以看到我将最长的序列放入匹配字典中，它是正确的，但是当我尝试将它与没有名称键的数据库副本进行比较时，我没有得到任何命中。
