Python: find a series of Chinese characters within a string and apply a function

Question

I\'ve got a series of text that is mostly English, but contains some phrases with Chinese characters. Here\'s two examples:

s1 = \"You say: 你好. I say: 再見\"
s         


        

Answer 1

A possible solution is to capture everything, but in different capture groups, so you can differentiate later if they're in Chinese or not.

ret = re.findall(ur'([\u4e00-\u9fff]+)|([^\u4e00-\u9fff]+)', utf_line)
result = []
for match in ret:
    if match[0]:
        result.append(translate(match[0]))
    else:
        result.append(match[1])

print(''.join(result))
