Python Unicode：如何针对Unicode字符串进行测试

Question

I have a script like this:

#!/Python26/
# -*- coding: utf-8 -*-

import sys
import xlrd
import xlwt

argset = set(sys.argv[1:])

#----------- import ----------------
wb = xlrd.open_workbook("excelfile.xls")

#----------- script ----------------
#Get the first sheet either by name
sh = wb.sheet_by_name(u'Data')

hlo = []

for i in range(len(sh.col_values(8))):
   if sh.cell(i, 1).value in argset:
        if sh.cell(i, 8).value == '':
            continue
        hlo.append(sh.cell(i, 8).value)

excelfile.xls contains unicode strings and I want to test against these strings from command line:

C:\>python pythonscript.py päätyö
pythonscript.py:34: UnicodeWarning: Unicode equal comparison failed to convert both arguments to
icode - interpreting them as being unequal
  if sh.cell(i, 1).value in argset:

How should I modify my code for Unicode?

Answer 1

Python has a sequence type called unicode which will be useful here. These links contain more information to help you regarding this:

• Python Unicode HOWTO
• Python built-in types (See section 6.6).

Answer 2

Try encoding the Excel unicode to string using cp1252 (windows default unicode) and then testing. I know a lot of people don't recommend this, but this is what sometimes solve my problems.

Pseudo=> if sh.cell(i, 1).value.encode('cp1252') in argset: ...
