Python自动化脚本编写技巧

```python
import os
# 设置目标目录
target_dir = "/path/to/directory"
# 遍历目录下的所有文件
for root, dirs, files in os.walk(target_dir):
    for file in files:
        # 判断文件名是否以".txt"结尾
        if file.endswith(".txt"):
            # 处理文件
            file_path = os.path.join(root, file)
            print(f"Processing file: {file_path}")
            # 在这里添加具体的处理逻辑
```

```python
def process_text_file(file_path):
    """处理文本文件"""
    with open(file_path, "r") as file:
        content = file.read()
        # 在这里添加具体的处理逻辑
        print(f"Processing content: {content}")
# 调用函数处理文件
process_text_file("/path/to/file.txt")
```

```python
try:
    # 尝试执行可能会引发异常的代码
    response = requests.get("http://example.com")
    response.raise_for_status()  # 如果请求失败，则抛出HTTPError异常
    # 在这里添加处理响应的逻辑
except requests.HTTPError as e:
    # 处理HTTP错误
    print(f"HTTP Error occurred: {e}")
except requests.RequestException as e:
    # 处理其他请求异常
    print(f"Request Exception occurred: {e}")
except Exception as e:
    # 处理其他异常
    print(f"An error occurred: {e}")
```

```python
import logging
# 配置日志记录
logging.basicConfig(level=logging.INFO, format="%(asctime)s - %(levelname)s - %(message)s")
# 在脚本中记录日志
logging.info("Starting script execution")
try:
    # 执行可能会引发异常的代码
    pass  # 在这里添加具体的代码
except Exception as e:
    logging.error(f"An error occurred: {e}")
logging.info("Script execution completed")
```
