Python 字符串清理 + 操作(重音字符)

Question

我有一个充满名字的数据库，例如:

John Smith  
Scott J. Holmes  
Dr. Kaplan  
Ray's Dog  
Levi's  
Adrian O'Brien  
Perry Sean Smyre  
Carie Burchfield-Thompson  
Björn Árnason

有一些带重音的外国名字需要转换成非重音字符的字符串。

我想将全名(在去除“'”、“-”等字符后)转换为用户登录名，例如:

john.smith  
scott.j.holmes  
dr.kaplan  
rays.dog  
levis
adrian.obrien  
perry.sean.smyre
carie.burchfieldthompson  
bjorn.arnason

到目前为止我有:

Fullname.strip()  # get rid of leading/trailing white space
Fullname.lower() # make everything lower case


... # after bad chars converted/removed
Fullname.replace(' ', '.') # replace spaces with periods
