打印换行但没有空格

Question

我正在解析一个 json 列表并在 txt 文件中打印 X 值。问题是我需要排除特定值，这样做会在列表中留下空白，如下所示：

我想删除那些换行符，但我能找到的使用 end='' 执行此操作的唯一方法基本上删除了包括换行符在内的所有内容，结果如下所示：

这是我正在使用的代码：

import json

with open('file.json') as json_file:
    data = json.load(json_file)

exclude = ['FFFFFFFFFFFFFFFFFFFFFFFFFFFF', 'BBBBBBBBBBBBBBBBBBBBBBBBBBBBB', 'AAAAAAAAAAAAAAAAAAAAAAAAA', 'ZZZZZZZZZZZZZZZZZZZZZZZZZZZZ']

with open("output.txt", "a") as f:
    for i in range(len(data)):
        if data[i]['owner'] in exclude:
            data[i]['owner'] = ''
        print (data[i]['owner'], end='', file=f)

如有任何帮助，我们将不胜感激！谢谢

Answer 1

看起来常规打印语句应该与 else 语句一起使用：

with open("output.txt", "a") as f:
    for i in range(len(data)):
        if data[i]['owner'] in exclude:
            data[i]['owner'] = ''
        else
            print (data[i]['owner'], file=f)

Answer 2

您将需要跳过一些迭代以跳过不需要的值。您仍然可以使用 '\n' 作为分隔符！

with open("output.txt", "a") as f:
    for i in range(len(data)):
        if data[i]['owner'] in exclude:
            continue
        print (data[i]['owner'], end='\n', file=f)

Answer 3

我只是建议不要打印任何内容，以防字符串是应该排除的字符串。

with open("output.txt", "a") as f:
    for entry in data:
        if entry['owner'] in exclude:
            continue
        print (entry['owner'], file=f)

打印换行但没有空格

Printing with newlines but no empty spaces
