編寫程序並需要一些輸入

Question

我正在做一個關於創建一個關於高爾夫的文件的程序，它只允許一個 For. 當我運行程序時，我收到關於 Golf_File.write(Name + ("\\n") ValueError: I/O operation on closed file 的錯誤。

Num_People = int(input("How many golfers are playing?: "))
Golf_File = open('golf.txt', 'w')

for count in range(1,Num_People+1):
    Name = input("Enter the player's name: ")
    Score = int(input("Enter the player's score: "))
    Golf_File.write(Name + ("\n"))
    Golf_File.write(str(Score) + ("\n"))

    Golf_File.close()

Answer 1

以下將起作用：

Num_People = int(input("How many golfers are playing?: "))
Golf_File = open('golf.txt', 'w')

for count in range(1,Num_People+1):
    Name = input("Enter the player's name: ")
    Score = int(input("Enter the player's score: "))
    Golf_File.write(Name + ("\n"))
    Golf_File.write(str(Score) + ("\n"))

Golf_File.close()

該文件應該在for循環之外關閉

Answer 2

通常認為使用with語句來處理文件對象更好

Num_People = int(input("How many golfers are playing?: "))

with open('golf.txt', 'w') as Golf_File:
    for count in range(1,Num_People+1):
        Name = input("Enter the player's name: ")
        Score = int(input("Enter the player's score: "))
        Golf_File.write(Name + ("\n"))
        Golf_File.write(str(Score) + ("\n"))
