regex - Python: Check if a string contains chinese character?

Question

A string maybe this

ipath= "./data/NCDC/上海/虹桥/9705626661750dat.txt"

or this

ipath = './data/NCDC/ciampino/6240476818161dat.txt'

How do I know the first string contains chinese?

I find this answer maybe helpful: Find all Chinese text in a string using Python and Regex

but it didn't work out:

import re
ipath= "./data/NCDC/上海/虹桥/9705626661750dat.txt"
re.findall(ur'[u4e00-u9fff]+', ipath) # => []

Answer 1

The matched string should be unicode as well

>>> import re
>>> ipath= u"./data/NCDC/上海/虹桥/9705626661750dat.txt"
>>> re.findall(r'[u4e00-u9fff]+', ipath)
[u'u4e0au6d77', u'u8679u6865']
