【问题讨论】：

你卡在哪里了？ Python 输出格式和字符串操作在许多地方都有在线记录。给您带来问题的代码在哪里？
你确定吗？这看起来更像是一个 csv 文件。
是的，这是我从 excel 导出的 csv 文件。我想编辑格式，删除逗号分隔符并在每种数据类型之间添加一个特定的值（空格）。
你能分享一下你到目前为止的尝试吗？

【解决方案1】：

您可以尝试从这里开始：

import sys

inFile = sys.argv[1]

outFile = "newFile.txt"

with open(inFile, 'r') as inf, open(outFile, 'w') as outf:

        for line in inf:
            line = line.split(',')
            print(line)

其中 sys argv[1] 是从命令行运行 python 脚本时 txt 文件的名称。

您可以看到它将打印出一个列表，其中包含您在 txt 数据文件中的逗号分隔符之间的各个字符串。从那里您可以进行列表操作来格式化数据。然后像这样写到outf（例子）：

# do what ever manipulations here to the output line 

output_line = line[0] + " " + line[1]
                outf.write(output_line)
                outf.write('\n'
