数据不会打印到文件中，从而导致文件为空

import os

# 确保目录存在
directory = 'path/to/directory'
if not os.path.exists(directory):
    os.makedirs(directory)

# 写入文件
file_path = os.path.join(directory, 'output.txt')
with open(file_path, 'w') as file:
    file.write('Hello, World!')

import os

# 检查文件权限
file_path = 'path/to/output.txt'
if not os.access(file_path, os.W_OK):
    print("Permission denied")
else:
    with open(file_path, 'w') as file:
        file.write('Hello, World!')

# 错误的代码示例
data = 'Hello, World!'
# 缺少写入文件的代码

# 正确的代码示例
data = 'Hello, World!'
file_path = 'path/to/output.txt'
with open(file_path, 'w') as file:
    file.write(data)
