The rise of artificial intelligence and big data concepts has led to the rapid growth of Python--python language logic concise, easy to get started, ecological rich, almost become a few emerging areas of choice. In addition to these two areas, Python has more areas of application: Crawler, Web, automated operations and other fields are very suitable for Python to play. Python jobs are getting more and more expensive as the gap in Python talent increases. With Marco Education recently graduated c

this pattern can also be written as /p (Erl|ython)/ You can also specify duplicates in the pattern. /ab+c/matches a string with one or more b followed by a C. Replace the + number with the * number, the regular expression created by/ab*c/is Match a A followed by 0 or more b followed by a C. You can also match a set of characters in a pattern. The commonly used character type example has \s, it matches a white space character (Space,tab, line break, etc.); \d matches any number; \w matches

want to learn programming-or want to understand computer technology-you have to master the command line. Going deep into the command line will teach you a lot about how computers work and manage information. You may find that some common mouse operations are faster. More importantly, you will be more likely to understand programming languages like Python and software like Git, requiring a little command line basis. Once you are familiar with the command line, you can break the barriers that hav

tasks is to provide a boot animation without using the Linux kernel or a user space tool like plymouth. A more common second-stage Boot Loader task is to provide network-based boot or make the disk connected to PCI available. In that case, a third-stage boot loader, such as GRUB, may be necessary for the system to run. Most importantly, the boot loader loads the Linux kernel and starts running it. If the first-stage Boot Loader does not provide a mechanism to pass kernel parameters at startup,
