Question

现在我知道有很多问题就像这个问题一样，我已经查看了所有这些问题并尝试了解它们，但我不能将它应用到我的情况中。基于之前对其他人的问题的回答，我提出了一些改进的代码。但它存在问题：

import sys
import os
import csv

def writefile():
    print('Please enter the following: ')
    a = input('Date Of The Fixture: ')
    b = input('Stadium: ')
    c = input('Opposition: ')
    d = input('Goals For Leicester: ')
    e = input('Goals Against Leicester: ')
    f = input('Attendance: ')
    with open("LCFC_League_Results.csv","w") as outfile:
        outfile.write('Date of the Fixture, Stadium, Opposition, Goals for Leicester, Goals Against Leicester, Attendance\n')
        for row in zip('Date of the Fixture', 'Stadium', 'Opposition', 'Goals for Leicester', 'Goals Against Leicester', 'Attendance'):
            outfile.write('{}, {}, {}, {}, {}, {}\n'.format(a,b,c,d,e,f))
    Main()

def readfile():
    myFile = open("LCFC_League_Results.csv","r")
    print("Reading File ...")
    print(myFile.read())
    myFile.close()
    Main()

def Main():
    print("Write To File - A")
    print("Read The File - B")
    print("Clear File - C")
    print("Exit The Program - X")
    Choice = input("What would you like to do with the file: ")

    if Choice == "a" or Choice == "A":
        x = int(input("How many matches do you want to input? "))
        y = 0
        while y<x:
            writefile()
            y = y+1

    elif Choice == "B" or Choice == "b":
        readfile()

    elif Choice == "C" or Choice == "c":
        os.remove("LCFC_League_Results.csv")
        Main()

    elif Choice == "X" or Choice == "x":
        sys.exit()


Main()

有问题的部分是子程序＆＃39; writefile＆＃39;下的内容。如果输入数据a，b，c，d，e，f，输出结果如下：

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
a, b, c, d, e, f
a, b, c, d, e, f

为什么输出7行;我输入了一次信息，想要一行。在加号上，至少列标记。作为一方而言，当它询问时，您要输入多少匹配？＆＃39;，无论您输入什么号码，它始终只允许您输入1组数据。这是另一个问题。

任何帮助将不胜感激;感谢。

Answer 1

每次调用您的函数Main()时，您正在重置y的值。

所以流程是这样的：

程序启动，Main()运行。
用户提供号码2。 y等于0 -
现在调用函数Writefile。完成后，它再次调用Main()。
现在另一个y，而不是您原来的y设置为0.
根据用户的回答，只要y被调用，新的0就会设置为Main()。

另外，你应该改变：

outfile.write('Date of the Fixture, Stadium, Opposition, Goals for Leicester, Goals Against Leicester, Attendance\n')
for row in zip('Date of the Fixture', 'Stadium', 'Opposition', 'Goals for Leicester', 'Goals Against Leicester', 'Attendance'):
    outfile.write('{}, {}, {}, {}, {}, {}\n'.format(a,b,c,d,e,f))

简单地说：

outfile.write('Date of the Fixture, Stadium, Opposition, Goals for Leicester, Goals Against Leicester, Attendance\n')
outfile.write('{}, {}, {}, {}, {}, {}\n'.format(a,b,c,d,e,f))

这仍然存在标题永远都会写的问题......

还有一点，您要导入模块csv，为什么不使用它？最后，如果你继续使用python，请阅读pep-8。

Answer 2

您的代码在这里写了七行：

for row in zip('Date of the Fixture', 'Stadium', 'Opposition', 'Goals for Leicester', 'Goals Against Leicester', 'Attendance'):
    outfile.write('{}, {}, {}, {}, {}, {}\n'.format(a,b,c,d,e,f))

如果您只想要一行，请删除for循环。
