The Python Package Index, abbreviated as PyPI (/ ˌ p aɪ p i ˈ aɪ /) and also known as the Cheese Shop (a reference to the Monty Python's Flying Circus sketch "Cheese Shop"), [2]: 8 [3]: 742 is the official third-party software repository for Python. [4] It is analogous to the CPAN repository for Perl [5]: 36 and to the CRAN repository for R.
In computing, a directory is a file system cataloging structure which contains references to other computer files, and possibly other directories. On many computers, directories are known as folders , or drawers , [ 1 ] analogous to a workbench or the traditional office filing cabinet .
where name_of_directory is the name of the directory one wants to create. When typed as above (i.e. normal usage), the new directory would be created within the current directory. On Unix and Windows (with Command extensions enabled, [15] the default [16]), multiple directories can be specified, and mkdir will try to create all of them.
Normally, this example would result in a bounds check when the element is read from the array and a second bounds check when the modified element is stored using the same array index. Bounds-checking elimination could eliminate the second check if the compiler or runtime can determine that neither the array size nor the index could change ...
This folder contains one subfolder for each user that has logged onto the system at least once. In addition, it has two other folders: " Public " and " Default " (hidden). It also has two folder like-items called "Default User" (an NTFS junction point to "Default" folder) and "All Users" (a NTFS symbolic link to " C:\ProgramData ").
In fact, files in a virtual folder do not even need to be stored as files on the hard drive. They may be on a network share or in a custom application datastore such as e-mail inbox or even a database. Documents cannot be "stored" in a virtual folder, since physically a virtual folder is just a file storing a search query.
An array data structure can be mathematically modeled as an abstract data structure (an abstract array) with two operations get(A, I): the data stored in the element of the array A whose indices are the integer tuple I. set(A, I, V): the array that results by setting the value of that element to V. These operations are required to satisfy the ...
Each thread reading from a database gains ownership of an element in a shared memory array, which it may update to indicate when it is within a transaction. Writers scan the array to determine the oldest database version the transaction must preserve without requiring direct synchronization with active readers.
