为文件中的txt文件将多行结果转换为单行

def convert_to_single_line(file_path):
    # 打开文本文件
    with open(file_path, 'r') as file:
        lines = file.readlines()
    
    # 处理多行结果
    result_lines = [line.strip() for line in lines if line.strip()]
    
    # 转换为单行
    single_line = ' '.join(result_lines)
    
    # 保存结果
    with open(file_path, 'w') as file:
        file.write(single_line)

# 调用函数并传入txt文件路径
convert_to_single_line('example.txt')
