A Python library that provides an easy way to identify devices like mobile phones, tablets and their capabilities by parsing (browser) user agent strings.
目前的解析是大小写敏感的，能否改进成大小写不敏感的？
例如：
mozilla/5.0 (windows nt 10.0; wow64) applewebkit/537.36 (khtml, like gecko) chrome/80.0.3987.87 safari/537.36 se 2.x metasr 1.0
能识别为：PC / Windows 10 / Sogou Explorer 1.0
而转换成小写后
mozilla/5.0 (windows nt 10.0; wow64) applewebkit/537.36 (khtml, like gecko) chrome/80.0.3987.87 safari/537.36 se 2.x metasr 1.0
只能识别为 other
