hard disk partitions, we know that the total number of primary partitions (including extended partitions) cannot exceed four, nor can we enclose extended Partitions between primary partitions. According to this principle, it is easier to divide hard disk partitions and reduce unnecessary troubles in the future;
1. Use fdisk-L to view the number of hard disks mounted to the machine and the partition information;
[Root @ localhost beinan] # fdisk-l
Disk/dev/hda: 80.0 GB, 80026361856 bytes
255 hea
must know how to view the partition information of a hard disk and format it accordingly. For example, you can use fdisk-L to view the partition information;
Refer to: Linux disk partition, file system, usage commands and related tools
For example, if I want to format a partition in a mobile USB flash drive, the panorama should be:[Root @ localhost beinan] # fdisk-lDisk/dev/hda: 80.0 GB, 80026361856 bytes255 heads, 63 sectors/track, 9729 CylindersUnits = cylinders of 16065*512 = 8225280 bytesDe

Output
For each test case, the result of sorting the separated integers is output. Two Adjacent integers are separated by a space. Each group of output occupies one row.

We can see that the system is installed in/dev/hda8; there is also a 56 GB disk partition/dev/sda1 mounted in/mnt/sda1; for other parameters, see man DFIi. fdsik

, the problem came out. Let's take China as an example. There are tens of thousands of Chinese characters. What should I do?The existing 8 bits one-byte system is the foundation and cannot be damaged. It cannot be changed to 16 bits or the like. Otherwise, the change is too large and you can only take another path: multiple ascii characters are used to represent one other Character, that is, MBCS (Multi-Byte Character System, Multi-Byte Character System ).With the concept of MBCS, we can represe
that too much encoding made the world too complicated and painful, so they sat together and shoot their heads to come up with a method: all the characters in the language are represented by the same character set, this is Unicode.
The original Unicode Standard UCS-2 uses two bytes to represent a single character, so you can often hear Unicode uses two bytes to represent a single character. But soon some people think that 256*256 is too small, or not

region you set. in Linux, MBCS cannot be used as the encoding. In Windows, you cannot see the MBCS characters, because Microsoft uses ANSI to scare people in order to make them more foreign. In the Save As dialog box of notepad, the encoding ANSI is MBCS. At the same time, GBK is used in the default region settings of Simplified Chinese Windows.
1.3. Unicode
Later, some people began to think that too much encoding made the world too complicated and painful, so they sat together and shoot their
result range is 0x0000 to 0xFFFFF.
The high 10 bits of the result and the 0xd800 do the logic or operation, the lower 10 bits and the 0xdc00 do the logic or the operation.
Combining the two parts together is the UTF-16 encoding of the character value.
The UTF-8 encodes Unicode using one byte or two bytes or three bytes.0xxxxxxx, using a byte to represent a Unicode code point that can represent 128 characters.110xxxxx 10xxxxxx, which represents a Unicode code point using two bytes a
This article mainly introduces the python natural language encoding and conversion module codecs. codecs is specially used for encoding and conversion. its interface can be used to expand to other code conversions, if you need it, you can refer to python's support for multi-language processing. it can process any character encoded in the current situation. here, I will take a deeper look at python's handling of multiple different languages.
One thing to note is that when python needs to perform
