尝试使用StringIO将以下字符串读取为文件,但出现以下错误.我该如何解决?
Trying to read following string as file using StringIO but getting the error below. How can I resolve it?
>> from io import StringIO >>> >>> datastring = StringIO("""\ ... Country Metric 2011 2012 2013 2014 ... USA GDP 7 4 0 2 ... USA Pop. 2 3 0 3 ... GB GDP 8 7 0 7 ... GB Pop. 2 6 0 0 ... FR GDP 5 0 0 1 ... FR Pop. 1 1 0 5 ... """) Traceback (most recent call last): File "<stdin>", line 9, in <module> TypeError: initial_value must be unicode or None, not str推荐答案
您可以通过在字符串之前添加一个u以使字符串成为unicode来解决错误:
You can resolve the error by simply adding a u before your string to make the string unicode:
datastring = StringIO(u"""\ Country Metric 2011 2012 2013 2014 USA GDP 7 4 0 2 USA Pop. 2 3 0 3 GB GDP 8 7 0 7 GB Pop. 2 6 0 0 FR GDP 5 0 0 1 FR Pop. 1 1 0 5 """)您的初始值应为Unicode .
