我有从for循环创建的字典。如何将它们全部添加到同一for循环下的列表中？

Question

使用下面的代码，我从“ for”循环中获得了单个词典（“ revised_user_dict”）。但是“ user_list”仅显示最后一个字典。像这样：

void sub (string str1, string str2){
    int i,j,k;
    for(i=0; i<=str2.size() ; i++){   
        for(j=0; j<=str1.size() ; j++ ){ 
            if( str2[i] == str1[j] )
                str1[j] = NULL;
        }
    }
    cout<<str1;

[{A:B, C:D, E:F}, {A:B, C:D, E:F}, {A:B, C:D, E:F}, {A:B, C:D, E:F}, {A:B, C:D, E:F}...]

如何拥有

这样的列表

user_list = []
revised_user_dict = {}
for user_dict in users_info:

    first_name  = user_dict["firstName"]
    last_name = user_dict["lastName"]
    email = user_dict["email"]
    role = user_dict["role"]

    revised_user_dict["first_name"] = first_name
    revised_user_dict["last_name"]=last_name
    revised_user_dict["email"] = email
    revised_user_dict["role"] = role

    user_list.append(revised_user_dict)

    print(user_list)
