I have some excel files with extensions that are xls，when I use xlrd to open these files, it failed，I do not know how to solve it.
oldbook=xlrd.open_workbook('file.xls')
oldsheet=oldbook.sheets()[0]

PS C:\Users\我是猫\Desktop\python>
Try overriding the encoding used:
oldbook = xlrd.open_workbook('file.xls', encoding_override="cp1252")
You can also try encoding_override="utf-8", play around with the encoding till you get the right one.

I am trying to save control identifiers to a variable.
The reason is that: i use main_dlg.print_control_identifiers(filename="control_ids.text") but i am getting this error:
Traceback (most recent call last):

return codecs.charmap_encode(input,errors,encoding_table)
UnicodeEncodeError: 'charmap' codec can't encode characters in position 71-76: c
haracter maps to <undefined>
because the program i am trying to control has greek characters inside.
So, i decided to save the control identifiers to a variable and then save it with the right encoding to a txt file.
A simple solution i thought is:
from pywinauto.application import Application
import os
app = Application(backend="uia").start("C:/python/Lib/site-packages/QtDesigner/designer.exe")
main_dlg = app.QtDesigner
main_dlg.wait('visible')
main_dlg.print_control_identifiers()
and then:
python script_name.py > output.txt
after that in output.txt file there are the control identifiers of the program (in this example QtDesigner).
The information I got as follows.

any one knows why this happened?
I do not know python, but the problem seems solved afterI made the modification to the line 158 of MultiLanguage.py(in the get_current_string method):
ret = ret.encode(self.encoding)
to the following line:
ret = ret.encode("utf8") #self.encoding
Hope this helps people who encounter the same problem.
Take a look at the versions of NDK and SDK, NDK. The recommended version is R17 - R19

The file I'm trying to import is this one.
Is that an encoding problem or some character in the file is causing this? What would be the way to solve it?
pd.read_excel('data.csv' encoding='utf-8')
#astrobiologist gave a good hint
Since I didn't want the hassle of going into patches, the way I found to solve was to open the file in Open Office and save it as an Excel 97 file. Finally worked
I'm running into this bizarre problem where when I run
from tensorflow.examples.tutorials.mnist import input_data

>>> f = tf.gfile.Open('/home/fqiao/development/MNIST_data/train-images-idx3-ubyte.gz', 'rb')

Anyone has any idea what's going on?
My system: Ubuntu 15.10 x64 python 3.5.0.
The bug has been addressed by a recent change 555e73d. MNIST files need to be opened with binary 'rb' mode instead of just text 'r'.
In my case, the problem was in the encoding of the data file.
Open the file using vim and execute:
:set fileencoding=utf-8
That solved the issue in my case.

Please advise me.
This is a bug in Python 2.7, reported as issue 21138; the mimetypes module doesn't use the correct encoding for Unicode mimetypes in the Windows registry.
The bug ticket contains a work-around; you'll have to edit mimetypes.py.
