写入文本文件时如何水平打印？

Question

我正在尝试在文本文件中打印出这样的输出：

Bruce Wayne
5 5 0 0 100 15
Jessica Jones
12 0 6 6 10 6
Johnny Rose
6 2 0 4 20 10
Gina Linetti
7 4 0 3 300 15
Buster Bluth
3 0 2 1 50 1

但是在我的代码上，

def write_to_file(filename, player_list):
    outfile = open(filename, "w")

    for i in range(len(player_list)):
        for j in player_list[i]:
           outfile.write(str(j) + '\n')

    outfile.close()

它是这样打印的：它像这样打印出来：

Bruce Wayne
5
5
0
0
100
15
Jessica Jones
12
0
6
6
10
6
Johnny Rose
6
2
0
4
20
10
Gina Linetti
7
4
0
3
300
15
Buster Bluth
3
0
2
1
50
1

player_list = [['Bruce Wayne', 5, 5, 0, 0, 100, 15], ['Jessica Jones', 12, 0, 6, 6, 10, 6], ['Johnny Rose', 6, 2, 0, 4, 20, 10], ['Gina Linetti', 7, 4, 0, 3, 300, 15], ['Buster Bluth', 3, 0, 2, 1, 50, 1]]

我不确定如何使底部排像上面的输出一样水平打印。我不允许使用任何列表功能，并且我必须使用循环，如我的代码所示。谢谢你！

Answer 1

您不能将player_list的所有内容都相同，因为这些值意味着不同的内容。第一个值是播放器名称，其余的是分数之类的。因此，您的代码需要在第一个值之后放置一个新线，但仅在其余部分之间（在第二行末尾有一个newline）。

尝试这样的事情：

def write_to_file(filename, player_list):
    outfile = open(filename, "w")

    for player_name, *scores in player_list:   # unpack first value separately
        outfile.write(player_name + "\n")
        outfile.write(" ".join(str(score) for score in scores) + "\n")
        
    outfile.close()

无关，您可能需要与一起使用来处理您的文件对象。即使有例外，它也会自动关闭文件：

with open(filename, "w") as outfile:
    for blah in ...:
        ...
# no need to manually call close(), it will happen automatically here

Answer 2

喜欢这样做

def write_to_file(filename, player_list):
    outfile = open(filename, "w")

    for i in range(len(player_list)):
        for j in player_list[i]:
           outfile.write(str(j))
        outfile.write('\n')

    outfile.close()

Answer 3

您需要将播放器名称与值分开。

def write_to_file(filename, player_list):
    outfile = open(filename, "w")

    for lst in player_list:
        player = lst[0]
        values = lst[1:]

        outfile.write(player + '\n' + " ".join([str(num) for num in values]) + '\n')


    outfile.close()
