Python的TXT文件级读写文件

Question

使用信息我与一般形式的TXT文件：

Last Name 
First Name 
Year 
Medal (This line only contains one number either 1,2,3 meaning gold,silver,bronze respectively) 

我试图做的是让用户输入一年算多少奖牌都当年获胜。然后还有一个功能，用户可以输入一个姓和名，函数应该打印出“约翰·史密斯赢得了一枚（1）金牌，1864年”

def medals(medalcount): 
    year= str(input("Please enter a year: ")) 
    with open("textfile") as f: 
      medalcount+=f.read().count(year) 
    return medalcount 

基本上我使用这个功能怎么算很多时候，用户输入的字符串年份出现在txt文件中。 至于下一部分我仍然对如何实际接近它感到困惑。

例子：

Smith 
John 
1896 
1 

>>> Please enter year: 1896 
15 medals won in this year 

Answer 1

def readFile(infilepath): 
    answer = {} 
    with open(infilepath) as infile: 
     for lastname in infile: 
      lastname = lastname.strip() 
      firstname = infile.readline().strip() 
      year = infile.readline().strip() 
      medal = infile.readline().strip() 

      if year not in answer: 
       answer[year] = {} 
      if lastname not in answer[year]: 
       answer[year][lastname] = {} 
      if firstname not in answer[year][lastname]: 
       answer[year][lastname][firstname] = {} 
      if medal not in answer[year][lastname][firstname]: 
       answer[year][lastname][firstname][medal] = 0 
      answer[year][lastname][firstname][medal] += 1 
    return answer 

def count(medalcounts): 
    year = input("What year would you like to check: ").strip() 
    answer = 0 
    for lastname in medalcounts[year]: 
     for firstname,medals in medalcounts[year][lastname].items(): 
      answer += sum(medals.values()) 
    print(answer, "medals were awarded in", year) 

    firstname = input("Enter first name: ").strip() 
    lastname = input("Enter last name: ").strip() 
    for year,yeard in medalcounts.items(): 
     medals = yeard[lastname][firstname] 
     for med,count in medals.items(): 
      print("In year", year, firstname, lastname, "won", count, '. gold silver bronze'.split()[med], "medals") 

用法：

count(readFile('path/to/file'))
