Python 将列表写入带格式的文本文档

Question

我需要能够 python 创建一个以特定方式显示列表的新文本文档，但我不确定如何在文本创建区域内使用格式

def write_to_file(filename, character_list):
### Using a while loop to iterate over the list of lists (characters).
index = 0
while index < len(character_list):
    with open("new_characters.txt", "w") as output:
        output.write(str(character_list))
    index = index + 1

上面的代码是我为在文本文档中显示完整列表所做的代码，但它只是将所有内容放在一行中。

我需要这样设置：

神奇女侠

戴安娜·普林斯

小时 5 5 0 0 90

蝙蝠侠

布鲁斯·韦恩

小时 6 2 0 4 80

而不是：

[['Wonder Woman', 'Diana Prince', 'h', 5, 5, 0, 0, 90], ['Batman', 'Bruce Wayne', 'h', 6, 2, 0, 4, 80],

这是上面发布的代码的输出。

并且代码必须在循环中！

Answer 1

试试这个方法：-

For 循环是更好的选择
使用\n换行

def write_to_file(filename, character_list):
    with open(f"{filename}.txt", "w") as output:
        for characters in character_list:
            for character in characters:
                character =str(character)
                output.write(character+("\n" if len(character)>1 else "" ))
                #output.write(character+("\n" if len(character)>1 else " " )) for  --> h 5 5 0 0 9 0

write_to_file('Any',[['Wonder Woman', 'Diana Prince', 'h', 5, 5, 0, 0, 90], ['Batman', 'Bruce Wayne', 'h', 6, 2, 0, 4, 80]])

输出：

Wonder Woman
Diana Prince
h550090
Batman
Bruce Wayne
h620480

Answer 2

试试这个。

def write_to_file(filename, character_list):
    ### Using a while loop to iterate over the list of lists (characters).
    index = 0
    while index < len(character_list):
        with open("new_characters.txt", "w") as output:
            for item in character_list:
                for character in item:
                    output.write(str(character) + '\n')
        index = index + 1

Answer 3

这适用于您以要求的格式显示的子集。

def write_to_file(filename, character_list):

    # open file with given filename, in 'write' mode
    with open(filename, 'w') as f:

        # iterate over characters in for loop
        # using tuple unpacking
        for (hero_name, char_name, *data) in character_list:

            # write hero and character names on a line each
            f.write(hero_name + '\n') # e.g. 'Wonder Woman'
            f.write(char_name + '\n') # e.g. 'Diana Prince'

            # convert all remaining elements to a string
            # using list comprehension
            data = [str(i) for i in data]

            # create a single string from a list of values separated by a space
            # using string join method on the list
            data = ' '.join(data)

            # write to file with newline
            f.write(data + '\n') # e.g. 'h 5 5 0 0 90'

其中的关键组成部分是 tuple unpacking, list comprehensions, and the string join method。我还包括了在打开文件时实际使用的文件名参数的使用。这意味着如果您还没有将带有扩展名的文件名传递给函数调用。
