import cannot be used inside eval

[阎兆珣]

   a = input("tell me which py to execute:  ")

   print(a)

   print('import '+a)

   print(type('import'+a))

   eval('print(a)')

   try:

       eval('import '+a)

   except Exception as e:

       print('Error: ', e)

   ##while True:

   ##    pass

   @python 3.4.2

   this code attempts to run a .py file that user specifies.

   eval() does fine with print() command

   but fails to call import command

   Is it a but or a taboo?

   Thanks
