During the two days of Asterisk performance testing, we often encounter the following error: "Too program open files ".
We know that in Linux, the file descriptor is a simple integer. Traditionally, the file descriptor of the standard input is 0, and the standard output is 1, the standard error is 2. POSIX defines stdin_fileno, stdout_fileno, and stderr_fileno to replace 0, 1, and 2. The definitions of these three symbolic constants are located in the
Extract sequence assignment to multiple objectsAny sequence (or an iterative object) can be extracted and assigned to multiple variables by a simple assignment statement. The only prerequisite is that the number of variables must be the same as the number of elements in the sequence.>>> data = [' ABCD ', ' a ', 1, 2, (3,4)]>>> a,b,c,d,e = Data>>> a,b,c,d,e(' ABCD ', ' a ', 1, 2, (3, 4))>>> a,b,c,d, (e,f) = data>>> F4>>>This decompression assignment can be used on any iterator object, not just a
; >>>a,b = Nudge,wink; or >>>[c,d] = [Nudge,wink] ; interchange can be so >>>nudge,wink = Wink,nudge. The original tuple and list assignment statements in Python are finally generalized and the right side can be any type of sequence, as long as the lengths are equal, for example:However, the sequence assignment statement actually supports any iterated object on the right, not just any sequence, which is a more general concept. However, to be more generic, you can use shards such as:Or the low en

Overview Purpose
Markdown aims to achieve "easy to read and write 」.
Readability is the most important in any case. A file written in Markdown format should be directly published in plain text, and does not seem to consist of many labels or format instructions. The Markdown syntax is influenced by some text-to-HTML formats, including Setext, atx, Textile, reStructuredText, Grutatext, and EtText. The biggest source of inspiration is the text email format.
