IOError: [Errno 22] invalid mode ('wb') or filename:

问题

I keep getting the following error.

IOError: [Errno 22] invalid mode ('wb') or filename: 'C:\\Users\\Viral Patel\\Documents\\GitHub\\3DPhotovoltaics\\Data_Output\\Simulation_Data\\Raw_Data\\Raw_Simulation_Data_2014-03-24 17:21:20.545000.csv'

I think it is due to the timestamp at the end of the filename. Any ideas?

回答1:

You cannot use : in Windows filenames, see Naming Files, Paths, and Namespaces ; it is one of the reserved characters:

• The following reserved characters:

  • < (less than)
  • > (greater than)
  • : (colon)
  • " (double quote)
  • / (forward slash)
  • \ (backslash)
  • | (vertical bar or pipe)
  • ? (question mark)
  • * (asterisk)

Use a different character not on the reserved character list.
