name.capitalize () capitalized 
name.casefold () all uppercase to lowercase 
name.center ( 50, " - " ) Output ' --------------------- ---------------------- of Li alex ' 
name.count ( ' lex ' ) lex statistical occurrences 
name.encode () format string encoded into bytes 
name .endswith ( " of Li " ) determines whether the string that ends of Li
  " Alex \ tLi " .expandtabs (10) outputs ' Alex of Li ' , the \ t converted into long spaces 
 name.find ( ' a ' ) to find a, find returns its index can not be found or -1
