datetime.strptime在PyQt4 QtGui.QWidget继承的类中不起作用

Question

For example I have this simple class:

from PyQt4 import QtGui, QtCore
import sys
from datetime import datetime

print datetime.strptime('Wed, 06-Feb-2014 12:05:12', '%a, %d-%b-%Y %H:%M:%S')

class Application(QtGui.QWidget):

    def __init__(self):
      super(Application, self).__init__()
      print datetime.strptime('Wed, 06-Feb-2014 12:05:12', '%a, %d-%b-%Y %H:%M:%S')

def main():

    app = QtGui.QApplication(sys.argv)
    ex = Application()
    sys.exit(app.exec_())


if __name__ == '__main__':
    main()  

When I run it I have the following output:

2014-02-06 12:05:12
Traceback (most recent call last):
  File "vkPlayListSync.py", line 23, in <module>
    main()    
  File "vkPlayListSync.py", line 18, in main
    ex = Application()
  File "vkPlayListSync.py", line 12, in __init__
    print datetime.strptime('Wed, 06-Feb-2014 12:05:12', '%a, %d-%b-%Y %H:%M:%S')
  File "/usr/lib/python2.7/_strptime.py", line 325, in _strptime
    (data_string, format))
ValueError: time data 'Wed, 06-Feb-2014 12:05:12' does not match format '%a, %d-%b-%Y %H:%M:%S'

so the first line with strptime , but the second call form the class __init()__ method throws error. I have not enough experience in Python and PyQt, so can't understand how to fix this. And I haven't found the answer here on stackoverflow or in google.

QApplication startup is altering your locale such that 'Wed, 06-Feb-2014 12:05:12' is no longer a valid date (ie the weekday and month names are in another language). Try running your application with LC_ALL="C" .
