Question

尝试写入文件并记录普通文本时出现错误。这是我的记录器输出：

Bad measurement: 40.74478609626E-9,81.48235294118E-9,163.01491596639E-9,244.51470588235E-9,326.05084670232E-9,407.55387700535E-9,489.09705882353E-9,570.63334914611E-9,652.15799632353E-9,733.68823529412E-9,815.19491596639E-9,1.30423299632E-6,2.60858733660E-6,6.11542963458E-6,13.04562372549E-6,26.09313266488E-6,39.13227058824E-6,52.17394175579E-6,78.25093569519E-6,163.01165588235E-6,305.64046063025E-6,611.30138063025E-6,815.07555294118E-6,1.01882401751E-3,1.22261084479E-3,2.44530079118E-3,9.9100E+037

Traceback (most recent call last):
  File "C:\Program Files\JetBrains\PyCharm Community Edition 2017.3.5\helpers\pydev\pydev_run_in_console.py", line 53, in run_file
    pydev_imports.execfile(file, globals, locals)  # execute the script
  File "C:/Projects/main.py", line 209, in <module>
    path = "data.txt"
  File "C:/Projects/main.py", line 177, in run_period
    logger.info("Error: {}".format(repr(e)))
IOError: [Errno 22] Invalid argument

上下文：我正在从示波器读取测量值并将其保存到文件中。有时，作用域中的数据将被破坏，因此我将写操作包装在try-catch中：

try:
    f.write(",".join(acq) + "\n")
    cnt += 1
except Exception as e:
    logger.info("Bad measurement: {}".format(",".join(acq)))
    logger.info("Error: {}".format(repr(e)))
    logger.info("The measurement couldn't be written to the file")

是的，我知道不好的做法是不使用特定的异常，但是我只是想获取数据并退出。

记录器已分配给

logging.basicConfig(format='%(message)s', level=logging.INFO)
logger = logging.getLogger("runScript")

我认为这可能与the Windows OS buffer limit有关，但是我的文件只有几百千字节。

引发错误的函数是PyCharm的一部分。功能如下：

def run_file(file, globals=None, locals=None, is_module=False):
    module_name = None
    entry_point_fn = None
    if is_module:
        file, _,  entry_point_fn = file.partition(':')
        module_name = file
        filename = get_fullname(file)
        if filename is None:
            sys.stderr.write("No module named %s\n" % file)
            return
        else:
            file = filename

    if os.path.isdir(file):
        new_target = os.path.join(file, '__main__.py')
        if os.path.isfile(new_target):
            file = new_target

    if globals is None:
        m = save_main_module(file, 'pydev_run_in_console')

        globals = m.__dict__
        try:
            globals['__builtins__'] = __builtins__
        except NameError:
            pass  # Not there on Jython...

    if locals is None:
        locals = globals

    if not is_module:
        sys.path.insert(0, os.path.split(file)[0])

    print('Running %s' % file)
    try:
        if not is_module:
            pydev_imports.execfile(file, globals, locals)  # execute the script
        else:
            # treat ':' as a seperator between module and entry point function
            # if there is no entry point we run we same as with -m switch. Otherwise we perform
            # an import and execute the entry point
            if entry_point_fn:
                mod = __import__(module_name, level=0, fromlist=[entry_point_fn], globals=globals, locals=locals)
                func = getattr(mod, entry_point_fn)
                func()
            else:
                # Run with the -m switch
                import runpy
                if hasattr(runpy, '_run_module_as_main'):
                    runpy._run_module_as_main(module_name)
                else:
                    runpy.run_module(module_name)
    except:
        traceback.print_exc()

    return globals

Python记录器抛出IOError：[Errno 22]无效的参数
