For example, the following Perl one-liner will reverse all the bytes in a file: perl -0777e 'print scalar reverse <>' filename While most Perl one-liners are imperative, Perl's support for anonymous functions, closures, map, filter (grep) and fold (List::Util::reduce) allows the creation of 'functional' one-liners.
Flow diagram. In computing, serialization (or serialisation, also referred to as pickling in Python) is the process of translating a data structure or object state into a format that can be stored (e.g. files in secondary storage devices, data buffers in primary storage devices) or transmitted (e.g. data streams over computer networks) and reconstructed later (possibly in a different computer ...
In Python, functions are first-class objects that can be created and passed around dynamically. Python's limited support for anonymous functions is the lambda construct. An example is the anonymous function which squares its input, called with the argument of 5:
A printing protocol is a protocol for communication between client devices (computers, mobile phones, tablets, etc.) and printers (or print servers).It allows clients to submit one or more print jobs to the printer or print server, and perform tasks such as querying the status of a printer, obtaining the status of print jobs, or cancelling individual print jobs.
The numbers whose trajectory under iteration of sum of squares of digits map includes 1. A007770: Factorial primes: 2, 3, 5, 7, 23, 719, 5039, 39916801, ... A prime number that is one less or one more than a factorial (all factorials > 1 are even). A088054: Wolstenholme primes: 16843, 2124679
Printing control characters were first used to control the physical mechanism of printers, the earliest output device. An early example of this idea was the use of Figures (FIGS) and Letters (LTRS) in Baudot code to shift between two code pages. A later, but still early, example was the out-of-band ASA carriage control characters. Later ...
The printing speed of serial dot matrix printers with moving heads varies from 30 [34] to 1550 characters per second (cps). [35] In a considerably different configuration, so called line dot matrix printers [36] or line matrix printers use a fixed print head almost as wide as the paper path utilizing a horizontal line of thousands of pins for ...
For example, in computer algebra systems such as Maxima or Mathematica the system may write output like "x ^ 2 + 3 * x" as " + ". Some graphing calculators , such as the Casio 9860 series , HP-49/50 series and HP Prime , TI-84 Plus , TI-89 , and TI-Nspire , the TI-83 Plus with the PrettyPt [ 1 ] add-on, or the TI-84 Plus with the same add-on or ...
