Vimgrep is a tool with Vim, which is similar to the use of grep. For example, to find word in the current directory, use the following: 1 : Vimgrep Word * If you want to recursively look up all the subordinate directories, then use the 1 : Vimgrep Word * * In addition, if you want to use a shortcut to find the letter under the current cursor, you only need to add the following code to the VIMRC: 1 2 3 4 5 6 "The settings fo

Default:y Specifies how-Export and Import manage the initial extent for table data. The default, compress=y, causes Export to flag table data for consolidation into one initial extent import. If extent sizes are large (for example, because of the pctincrease parameter), the allocated space would be larger than the Space required to hold the data. If you are specify Compress=n, Export uses the current storage parameters, including the values of initial extent size and

-locking, consistent read. However, the definition of snapshot data is not the same. Under the RC transaction isolation level, for snapshot data, non-conforming reads are always locked to the latest snapshot data of the row. At the RR transaction isolation level, for snapshot data, non-conforming reads always read the row data version at the beginning of the transaction. That is, the RC level will see the latest version of the data after other transactions are committed. The RR level always read

Find all starting indices of substring (s) in S that's a concatenation of each word in words exactly once and without any Intervening characters.For example, given:s: "Barfoothefoobarman", Words: ["foo", "Bar"]You should return the indices: [0,9].

iterator (iterator) protocol, the iterator Protocol needs to be implemented __iter__ , the next interface • Ability to pause the execution of code in a function body by repeatedly entering and returning multiple times Here's a look at the test code: >>> def gen_example (): ... print ' before any yield ' ... yield ' first yield ' ... print ' between yields ' ... yield ' sec Ond yield ' ... print ' no yield anymore ' ... >>> gen = gen_example () >>> Gen.next () # First Call Nextbefore any Yield

;> counter = count_iterator () >>> Next (counter) 0>>> Next (counter) 1>>> next ( Counter) 2>>> Next (counter) 3>>> list (counter) # This would result in an infinite loop! Finally, we will modify the above program: If an object does not have a __iter__ method but defines the __getitem__ method, the object is still iterative. In this case, when the Python built-in function Iter will return an iterator type corresponding to this object, and use the __getitem__ method to traverse all elements of t

. Other classes can do things that can be done by defining the exception class. However, the exception class is always designed to be very simple, and they provide properties that can be easily extracted from error handling. When designing a module to handle multiple exceptions, it is often necessary to define a basic class, and other classes to deal with some special cases on this basis. class Error (Exception): "" "," "" "" "" "" " Pass Class Inputerror (Error): "" "Exception raised for
