O‘Reilly出版的Wes McKinney编的《Python for Data Analysis》

 警告：ParserWarning: Falling back to the ‘python‘ engine because the ‘c‘ engine does not support regex separators (separators > 1 char and different from ‘\s+‘ are interpreted as regex)

解决方法：加上 engine=‘python‘

ratings = pd.read_table(‘data\ml-1m\\ratings.dat‘,sep=‘::‘,header=None,names=rnames,engine=‘python‘)
