an object that can be called by next() a function and continually returns the next value is called an iterator: Iterator . An object that can directly act on for a loop is called an iterative object: Iterable .forThere are several types of data that work directly on the loop:A class is a collection of data types, such as,,, list tuple , and dict set str so on;One is generator to include the generator and yield the generator function with the band.Collection data types such as list , dict ,, and
In the last time I went to France, I had posted a panorama of the Sky City "Saint Ray" in a very big way on a blog. Since I don't have a Sony NEX-5C camera with an automatic scanning panorama, this panorama is done with "multiple photos" + PS later splicing. However, and when I first took a panoramic picture must spend a lot of time seriously in Photoshop a little bit of stitching photos, this panorama of the actual production time is only 15 minutes.

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:

Rever commit: The record of the operation is saved, the commit record is automatically generated, and the revocation is in effect for the action commit record (for example, I have just submitted a code with a problem, to delete the newly submitted code)

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
