由 南笙酒味 提交于 2019-11-29 17:01:45
问题 I have inherited some code which is periodically (randomly) failing due to an Input/Output error being raised during a call to print. I am trying to determine the cause of the exception being raised (or at least, better understand it) and how to handle it correctly. When executing the following line of Python (in a 2.6.6 interpreter, running on CentOS 5.5): print >> sys.stderr, 'Unable to do something: %s' % command The exception is raised (traceback omitted): IOError: [Errno 5] Input/output

What can lead to “IOError: [Errno 9] Bad file descriptor” during os.system()?

由 时光总嘲笑我的痴心妄想 提交于 2019-11-27 20:59:09
I am using a scientific software including a Python script that is calling os.system() which is used to run another scientific program. While the subprocess is running, Python at some point prints the following: close failed in file object destructor: IOError: [Errno 9] Bad file descriptor I believe that this message is printed at the same time as os.system() returns. My questions now are: Which conditions can lead to this type of IOError? What does it exactly mean? What does it mean for the subprocess that has been invoked by os.system() ? You get this error message if a Python file was

Python's “open()” throws different errors for “file not found” - how to handle both exceptions?

由 一笑奈何 提交于 2019-11-27 19:16:34
I have a script where a user is prompted to type a filename (of a file that is to be opened), and if the file doesn't exist in the current directory, the user is prompted again. Here is the short version: file = input("Type filename: ") ... try: fileContent = open(filename, "r") ... except FileNotFoundError: ... When I tested my script on my MacOS X in Python 3.3x it worked perfectly fine when I type the wrong filename on purpose (it executes the suite under "expect"). However, when I wanted to run my code on a Windows computer in Python 3.2x, I get an error that says that "FileNotFoundError"

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

由 泪湿孤枕 提交于 2019-11-27 16:19:26
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) >
