python dict 以key名 去重运算

将日期相同的数据统计在一起

a_count = [

{'create_time': '2020-03-05', 'total_len': 1, 'count_invite': 1},

{'create_time': '2020-03-11', 'total_len': 2, 'count_invite': 2},

{'create_time': '2020-03-18', 'total_len': 2, 'count_invite': 2},

{'create_time': '2020-03-06', 'total_len': 1, 'count_invite': 1},

{'create_time': '2020-03-04', 'total_len': 1, 'count_invite': 1},

{'create_time': '2020-03-15', 'total_len': 2, 'count_invite': 2},

{'create_time': '2020-03-19', 'total_len': 1, 'count_invite': 1},

{'create_time': '2020-03-27', 'total_len': 3, 'count_invite': 3},

{'create_time': '2020-03-25', 'total_len': 64, 'count_invite': 59},

{'create_time': '2020-03-25', 'total_len': 3, 'count_invite': 2},

{'create_time': '2020-03-25', 'total_len': 1, 'count_invite': 1}
