biometric identifiers

function, and dict can be broken into the keyword parameters to the function (through and *). So you can easily pass a list/tuple/dict to the format Function. Very flexible.--------------------------------------Format qualifierIt has a rich "format qualifier" (syntax is {} with:), such as:Fill and alignPadding is used in conjunction with alignment^, : The fill character after the number, only one character, not specified by default is filled with a spaceLike whatIn []: ' {: >8} '. format (' 189

The operating system (either iOS or OS X) uses the bundle logo to uniquely identify your app. The bundle identity consists of an organization ID and the name of your app.In general, the organization ID is the reversal of your domain name. If your domain name is example.com then your organization ID will be com.example, and your MyApp bundle identifier will be com.example.MyApp.is hair a domain name reversal? This is because reversing the domain name in the Java world is a popular way to avoid na

Tcpdump captures TCP identifiers According to each 8-bit group, the TCP flag is located in the 13th 8-bit group, as shown in the following figure. The first row contains 32 digits ranging from 0 to 3 8-bit groups, the second row is a 4-7 eight-bit group, and the third row is a 8-11 eight-bit group. The first four of Data Offset + reserved are 12th eight-bit groups, in the reserved, the last 2 + 6 flag bits are 13th octal groups. The following TCP

Some rules for PHP variable identifiers

Comments:Single-line Comment://Multiline Comment:/* */Document Comment:/** */Where document comments can export dox documents, common Javadox tags are as follows:@author: Specify the author of the Java program@version: Specify the version of the source file@deprecated: Deprecated Code@param: Parameter description information for a method@return: The return value description information for the method@see: "See" for specifying poor reference content@throws: Throws an exception, with @exception ag

hbase tables are grouped by a column family named colomn family, and data is stored by column family on disks. For this reason, therefore, when defining an hbase table, apart from defining the table name, you must also define the column family. Traditional databases do not have column families.Column ID: data in a column family is described by a colomn qualifier. Column identifiers can be dynamically defined when you define a table or when saving dat

Several source code identifiers1. Oo indicates understanding of the entire project's OO architecture and may be reorganized.2. Important indicates that the current statement is a key call of the entire project function.3. Good tips useful in some languages or frameworks4. fixme marks the points I don't understand, or bugs to be fixed5. byme was changed to the official function or usage by me. Important also needs to be subdivided. Several source code ident
