文本预处理5-去除文字开头的空格

1.针对文本开头存在空格的问题进行处理。

2.读取txt文档，将处理后的内容写回原文件。

#文本预处理5-去除文字开头的空格
import os
def left_align_text(text): 
    # 将文本分割成行
    lines = text.split('\n')
    # 去除每行的前导空格并左对齐
    aligned_lines = [line.lstrip().ljust(len(lines[0])) for line in lines]
    # 将对齐后的行合并回文本
    aligned_text = '\n'.join(aligned_lines)
    return aligned_text


def process_txt_files(folder_path):
    for filename in os.listdir(folder_path):
        if filename.endswith('.txt'):
            file_path = os.path.join(folder_path, filename)
            with open(file_path, 'r', encoding='utf-8') as file:
                content = file.read()
                processed_content = left_align_text(content)

            # 将处理后的内容写回原文件
            with open(file_path, 'w', encoding='utf-8') as file:
                file.write(processed_content)

            # print(f'Processed content written back to {filename}')


# 替换为你的文件夹路径
folder_path = "C:\\Users\\lenovo\\Desktop"
