pathlib模块已添加到 Python 3.4 中,并具有可用于文件处理和系统路径的更有效方法。该模块中的read_text()函数可以读取文本文件并在同一行中将其关闭。以下代码显示了这一点。from pathlib import Path content = Path("sample.txt").read_text().replace('\n', ' '
withopen('sample.txt','r')asfile:content=file.read()cleaned_content=''.join(eforeincontentife.isalnum()ore.isspace())text_string=str(cleaned_content)print(text_string) 1. 2. 3. 4. 5. 6. 7. 运行上面的代码,我们将得到处理后的文本内容字符串: Hello this is a sample text file It cont...
