import

问题 I'm doing some patching of import statements, and I need to know exactly what members are imported by from m import * . The documentation seems to indicate that when __all__ is absent, all members will be imported that do not begin with an underscore. Is this exactly correct under all circumstances? I know that inspect.getmembers() , dir() , and m.__dict__ all have slightly different logic, so I'm not completely sure which (if any) will provide the same list as import * . 回答1: Let's take a

问题 I want to import a class that is in App_Code to use it in my aspx pages. How can I do it ? Thanks 回答1: Add the namespace you used to your codebehind file or aspx file(if not using code behind). using YourNamespace; //C# imports YourNamespace //VB or if not using codebehind <%@ Import Namespace="YourNamespace" %> 回答2: if your app_code class is in another namespace, add a using statement at the top of your code behind. Example: using MyCustomNamespace; EDIT: if using vb in your code behind:

问题 I'm trying to develop a simulation class that replaces serial at specific apps(Win7, python 2.7). I have a SerialHandle class that works in number of apps, It's job is add logic to the well known serial methods, the idea was to replace python serial.py with a dummy file with the same name so we won't have to change and imports at SerialHandle . Now i have this file with Serial class just like the origin and it works fine: serial.py ...Serial() Since i want to really simulate the methods i

问题 I have a folder with more than 2,000 rtf documents. I want to import them into r (preferable into a data frame that can be used in combination with the tidytext package). In addition, I need an additional column, adding the filename so that I can link the content of each rtf document to the filename (later, I will also have to extract information from the filename and save it into seperate columns of my data set). I came across a solution by Jens Leerssen that I tried to adapt to my

问题 I have a file with no extension with lines like this (ignore the spacing between the lines, but each line is a separate row): OrderedDict([('key1', u'value1'), ('key2', 'value2')]) OrderedDict([('key1', u'value1'), ('key2', 'value2')]) OrderedDict([('key1', u'value1'), ('key2', 'value2')]) when I import it to Python snap_fh = open("C:\Users\.......") for row in snap_fh: print(type(row)) rows are "strings" and I cannot parse it as an OrderedDictionary "OrderedDict([('key1', u'value1'), ('key2'

问题 When I try to import a named import, it fails silently if the name import does not exist. Is there a way to get webpack to fail loudly when it cannot find the import at build time For example: // file1.js const var1 = 'var1' export { var1 } and // file2.js import { var2 } from './file1' // at this point, var2 is undefined at runtime because it was never exported from file1.js Instead, I want it to fail at build time. Is there a webpack option or some other technique I can use to catch this
