本项目仅为自己的Python常用工具类。
其中有些是自己写的，有的则是网上找的，由于有些还需要copy代码到相应需求处才能使用，比如说放在gist或其他代码片段保存工具并不太方便，所以这里也构建一个库，用的时候先install然后直接import就好了。
- 彩色日志
- 获取系统可用tcp端口
- 从文件中逐行获取json对象
- 发送邮件
- 将时间间隔（s为单位）转换为日时分秒表示
- 将迭代器转化为批量数据返回形式
- 执行系统命令并获取执行结果
- 检查文件是否存在以及是否对应相应拓展名
- 获取文件名，不含拓展名
- 将迭代器截断，只返回前面部分
- 获取变量名
- 获取变量类型和属性信息
- 将可序列化对象以json格式写入文件中
- 比较两个字符串差异，高亮差异部分
- 根据项目名和当前脚本路径检测项目路径并添加至系统路径
- 读取yaml文件
- 终端彩色输出
from lightutils import logger
logger.info("info")
logger.warning('warning')
logger.debug('debug')
logger.error('error')效果如图：
from lightutils import get_free_tcp_port
port = get_free_tcp_port()
print(port)执行结果为：
49783
<class 'int'>从文件中逐行获取json对象，
from lightutils import read_json_line
for obj in read_json_line('test.json'):
print(obj)执行结果为：
{'info': {'word': '丘为', 'means': [['寻西山隐者不遇', '寻西山隐者不遇'], ['左掖梨花', '左掖梨花']]}, 'type': 'ambiguous'}
{'info': {'word': '丘为', 'means': [['寻西山隐者不遇', '寻西山隐者不遇'], ['左掖梨花', '左掖梨花']]}, 'type': 'ambiguous'}原文件内容为：
{"info": {"word": "丘为", "means": [["寻西山隐者不遇", "寻西山隐者不遇"], ["左掖梨花", "左掖梨花"]]}, "type": "ambiguous"}
{asdf}
{"info": {"word": "丘为", "means": [["寻西山隐者不遇", "寻西山隐者不遇"], ["左掖梨花", "左掖梨花"]]}, "type": "ambiguous"}错误输出日志error.log内容如下：
line2: {asdf}
使用Python发送一封邮件
from lightutils import send_email_notification
to = "[email protected]"
subject = "just a test"
contents = ["the test of lightUtils's send_email_notification function"]
result = send_email_notification(to, subject, contents)
if result:
print("发送成功！")
else:
print("发送失败！")发送成功！

主要应用场景是在一个项目中需要根据路径去添加和使用包，这里提供程序自动检测的功能，以使得不必操心具体相对路径位置，只要提供程序包名即可。
