[已解决]怎么实现把两个列表联合起来统计

937135952

假设这么一个场景，name里记录每次访客名字，date里记录每位访客访问日期。每位访客多次来访只计入1，要统计每日访客人数（重复不算）

1. name = ["张三","李四","王五”","李四","张三","李四","王五”]
   
2. date = ["01-03","01-03","01-03","01-03","01-02","01-02","01-01"]

复制代码

统计结果应该是：01-03：3人，01-02：两人，01-01：1人。
求出大佬们应该如何实现

1. name = ["张三", "李四", "王五", "李四", "张三", "李四", "王五"]
   
2. date = ["01-03", "01-03", "01-03", "01-03", "01-02", "01-02", "01-01"]
   
3. 
   
4. record = dict()
   
5. for d, n in zip(date, name):
   
6.     if d not in record:
   
7.         record[d] = [n]
   
8.     else:
   
9.         if n in record[d]:
   
10.             continue
    
11.         record[d].append(n)
    
12. for d, i in record.items():
    
13.     print("{}: {}人".format(d, len(i)))

每位访客每日多次来访只计入1

1. date = ["01-03","01-03","01-03","01-03","01-02","01-02","01-01"]
   
2. 
   
3. for i in range(10):
   
4.     x = f"01-0{i}"
   
5.     if x in date:
   
6.         print(f"{x}：{date.count(x)}人")

name列表好像完全没用到 只用到了date列表的次数记录吗

不是的，01-03只能计3人，因为李四是当天重复来访

1. name = ["张三", "李四", "王五", "李四", "张三", "李四", "王五"]
   
2. date = ["01-03", "01-03", "01-03", "01-03", "01-02", "01-02", "01-01"]
   
3. 
   
4. record = dict()
   
5. for d, n in zip(date, name):
   
6.     if d not in record:
   
7.         record[d] = [n]
   
8.     else:
   
9.         if n in record[d]:
   
10.             continue
    
11.         record[d].append(n)
    
12. for d, i in record.items():
    
13.     print("{}: {}人".format(d, len(i)))
