This article mainly introduces "how to understand Python grammar". In daily operation, I believe many people have doubts about how to understand Python grammar. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful for you to answer the doubts about "how to understand Python grammar". Next, please follow the editor to study!
The Python syntax integrated development environment includes many new and improved features to improve productivity. IDE has also been redesigned to provide developers with direct access to .NET Framework components, and we use Python instead of plug-ins in the form of dynamic link libraries.
However, this in itself makes most open source software inferior to the products of professional software companies such as Microsoft in coding ease of use and pertinence. Using open source software is more or less uncomfortable. Friends in earlier versions of Python grammar must have felt the same way. Sometimes it's not just uncomfortable, due to different software developers or versions, we can't guarantee that all software can be simply migrated between different machines.
This is especially true for some large software, such as ORACLE 8.0.5. In many cases, the system state, especially the kernel state, has a vital impact and restriction on the installation, use and performance of the program. On the other hand, we can also tailor the kernel for our computers.
In this way, there will be no big dustbins like Windows 98. To compile the kernel of Linux, you must first have a general impression of it. Linux is a replica of Unix, which supports multi-tasking, virtual memory, multi-terminal, virtual file system and other features.
The Python syntax * can run on 386 up to 486 personal computers, and other machines with architectures, such as SUN Sparc,M68000,DEC Alpha,PowerPC, have gradually come up with applicable Linux. There are many ways to configure the kernel, such as make config, make xconfig, make menuconfig, make oldconfig, and so on, all of which have the same function.
The difference should be seen by the name, except that make oldconfig refers to using the system's current setting (. / .config) as the default. Make menuconfig is used here. Keep in mind that the more drivers you don't need, the larger the kernel, which not only runs slowly and takes up a lot of memory, but in a few cases, it can cause other problems.
Some of the options that can be configured are:
1) code maturity level option code maturity prompt for development and/or incomplete code/drivers [NMongo?] If you are interested in testing some modules in the kernel that have not yet been completed, select y, otherwise select N, want to know more details? You will see the online help (below? An uppercase N indicates the default value.
2) processor type and features processor types and characteristics Processor family (386486qqx486586Universe K5ax 5x86ash 6x86Gen) [PPro/6x86MX] [] is the default value, which can be selected according to the results of the uname command described earlier. If this item is higher than 386, the generated kernel will not boot on the 386 machine.
3) the loadable model support loadable module supports Enable loadable module support (CONFIG_MODULES) [Y Universe?]
Select y, otherwise many modules that are only used for dynamic loading will not be available.
4) the general setting of general setup is Networking support (CONFIG_NET) [Y Universe?] Choose y, how many computers do not have to surf the Internet now?
5) plug and play support plug and play device support
Plug and Play support (CONFIG_PNP) [Nhampany?]
Choose y.
6) block devices block device Normal PC floppy disk support (CONFIG_BLK_DEV_FD) [Y _ Unix _ m _ Unix?]
A regular floppy drive. Select y. Enhanced IDE/MFM/RLL disk/cdrom/tape/floppy support (CONFIG_BLK_DEV_IDE) [Y _ Unip _ n _ Universe?]
The hard disk, optical drive, tape and floppy drive of these interfaces. Select y. Include IDE/ATAPI CDROM support (CONFIG_BLK_DEV_IDECD) [YUnimUnix?] CDROM. Select y.
7) networking options network option Packet socket (CONFIG_PACHET) [Y _ Unix _ m _ Unix?] According to the current situation of network development, it is better to choose y. Of course, you can choose something else. Kernel/User netlink socke (CONFIG_NETLINK) [Nhampany?] The kernel communicates with the user process in both directions. Select y. Network firewalls (CONFIG_FIREWALL) [Nhampany?]
If you really need to use a firewall, choose y. There are too many uses of UNIX domain sockets (confgi_unix) [YUnim confgi_unix?] socket. TCP/IP networking (CONFIG_INET) [YUnip nAccord?] Choose y for the same reason as above. The IPX protocol (CONFIG_IPX) [Ngamma Universe?] In fact, not so many people really need to use or learn IPX, so generally choose N.
8) SCSI support SCSI support, and SCSI low-level drives SCSI low-level drivers are selected according to the actual situation of SCSI devices in the system.
9) Networking device support network equipment supports that if you use LAN to access the Internet, choose the network card; if you use MODEM to dial up the Internet, it depends on the kind of service provided by ISP, which is usually PPP.
10) Amateur Radio support amateur radio supports what this is, so I choose Python grammar.
At this point, the study of "how to understand Python grammar" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
