打开 Pycharm 设置界面，依次点击 Editor → File and Code Templates → Python Script，输入自定义模板即可，参考如下：
#!/usr/bin/env python3
# -*- coding: utf-8 -*-
"""
@FileName: ${NAME}.py
@Function:
@Author: Zhihe An
@Site: https://chegva.com
@Time: ${DATE}
"""之后创建python文件就会按模板定义自动添加好头部信息啦
#!/usr/bin/env python3
# -*- coding: utf-8 -*-
"""
@FileName: hello world.py
@Function: Show me the world!

The following predefined variables can be used in file templates:
| Variable | Description |
|---|---|
${DATE} | Current system date |
${DAY} | Current day of the month |
${DIR_PATH} | Path to the directory of the new file (relative to the project root) |
${DS} | Dollar sign $. This variable is used to escape the dollar character, so that it is not treated as a prefix of a template variable. |
${FILE_NAME} | Name of the new file |
${HOUR} | Current hour |
${MINUTE} | Current minute |
${SECOND} | Current second |
${MONTH} | Current month |
${MONTH_NAME_FULL} | Full name of the current month (January, February, and so on) |
