同时替换掉多个字符串

import re  
def multiple_replace(text, adict):  
    rx = re.compile(‘|‘.join(map(re.escape, adict)))  
    def one_xlat(match):  
        return adict[match.group(0)]  
    return rx.sub(one_xlat, text) 

text = "Larry Wall is the creator of Perl" 
adict = {  
    "Larry Wall" : "Guido van Rossum",  
    "creator" : "Benevolent Dictator for Life",  
    "Perl" : "Python",  
}  
print multiple_replace(text, adict)
