Python - 何时使用文件vs打开

# 打开文件并创建文件对象
with open('file.txt', 'r') as file:
    # 读取文件内容
    content = file.read()

# 关闭文件对象
file.close()

# 使用文件作为函数的输入
def process_file(file_path):
    with open(file_path, 'r') as file:
        content = file.read()
        # 处理文件内容
        processed_content = process_content(content)

        # 写入新文件
        with open(file_path.replace('.txt', '-processed.txt'), 'w') as output_file:
            output_file.write(processed_content)

text_files = [
    'file1.txt',
    'file2.txt',
    'file3.txt',
]

process_file(*text_files)
