如何使用Python移除文本中的连字符并保留原有格式

需要编写Python函数，将带跨行连字符的文本转换为保留原有换行和缩进、且移除跨行连字符的格式：

输入文本：

text = '''hi guy-
     s how do i re-
      order this 
       text so it doesn-
        t have any "-" ele-
    ments and it is still i this form'''

预期输出：

text = '''hi guys
     how do i reorder
      this 
       text so it doesnt
        have any "-" elements
    and it is still i this form'''

之前尝试的代码未达到预期效果：

def uprav(text):
    zoz = ""
    text = text.split()
    print(len(text))
    for i in text:
        if i[-1] == "-":
            nove_slovo = i[:-1]
            zoz = zoz + nove_slovo 
        else:
            zoz = zoz + i + " "
    zoz.split()
    print(zoz)

原代码的核心问题是：

1. 使用text.split()拆分文本时，会将所有空白字符（换行、多空格）统一拆分，彻底丢失了原有的换行结构和每行缩进信息。
2. 处理逻辑仅拼接单词，无法保留原文本的行格式，最终输出是无结构的字符串。

要保留原文本的换行和缩进，需按行处理，识别跨行连字符并拼接对应的单词，同时保留行结构。以下是实现代码：

def fix_hyphenated_lines(text):
    lines = text.split('\n')
    result = []
    i = 0
    while i < len(lines):
        current_line = lines[i]
        # 检查当前行是否以连字符结尾
        if current_line.endswith('-'):
            # 去掉末尾的连字符
            prefix = current_line[:-1]
            i += 1
            if i >= len(lines):
                result.append(prefix)
                break
            next_line = lines[i]
            # 拆分下一行的前置空格、第一个单词和剩余内容
            leading_spaces = len(next_line) - len(next_line.lstrip())
            parts = next_line.split(maxsplit=1)
            if parts:
                first_word = parts[0]
                # 拼接前缀与第一个单词，作为新的行加入结果
                result.append(prefix + first_word)
                # 处理下一行的剩余内容：如果还有内容，保留缩进继续循环
                if len(parts) > 1:
                    lines[i] = ' ' * leading_spaces + parts[1]
                else:
                    i += 1
            else:
                result.append(prefix)
                i += 1
        else:
            result.append(current_line)
            i += 1
    return '\n'.join(result)

测试验证 #

调用函数测试输入文本：

text = '''hi guy-
     s how do i re-
      order this 
       text so it doesn-
        t have any "-" ele-
    ments and it is still i this form'''

print(fix_hyphenated_lines(text))

输出结果与预期完全一致：

hi guys
     how do i reorder
      this 
       text so it doesnt
        have any "-" elements
    and it is still i this form
