Share the python learning path

the first stage is Python foundation and Linux database. This is the beginning stage of python, and also an important stage to help students lay a good foundation. You need to master Python basic syntax rules and variables, logic control, built-in data structure, file operation, advanced functions, moles, common standard library moles, functions, exception handling, MySQL use, coroutine and other knowledge points

learning objectives: master basic Python syntax and basic programming ability; Master the basic operation commands of Linux, master the advanced content of MySQL, and complete the projects of bank ATM system, English Chinese dictionary, lyrics parser, etc

the second stage is full web stack. In this part, you need to master HTML, CSS, JavaScript, jQuery, bootstrap, web development foundation, Vue, flag views, flag template, database operation, flag configuration and other knowledge

learning objectives: master the web front-end technology content, master the web back-end framework, skillfully use flash, tornado, Django, and complete the data monitoring background project

The third stage is data analysis + artificial intelligence. This part is mainly to learn the knowledge points related to crawler. You need to master the knowledge of data capture, data extraction, data storage, crawler concurrency, dynamic web page capture, scrapy framework, distributed crawler, crawler attack and defense, data structure, algorithm, etc

learning objective: to master crawler, data acquisition, data organization and algorithm advanced and artificial intelligence technology. It can complete crawler attack and defense, image mosaic, movie recommendation system, earthquake prediction, artificial intelligence project and other stage projects

The fourth stage is advanced. This is a python advanced knowledge point. You need to learn project development process, deployment, high concurrency, performance tuning, go language foundation, blockchain introction, etc

learning objectives: master the technology of automatic operation and maintenance and blockchain development, and complete the automatic operation and maintenance projects, blockchain and other projects

according to the python learning roadmap above, you can basically become a qualified Python development engineer. Of course, if you want to quickly become the elite talents of enterprises, you need good teachers to guide you, and you need more projects to accumulate practical experience

3. EU CE certification (including EUP) - the pass for procts to enter the EU market

CE, as a compulsory qualification mark of the EU, greatly facilitates the export of Chinese procts
compared with other traditional voluntary safety certification in EU countries, all the electrical and electronic procts (except plug and socket) listed in [table 1] can be directly exported to EU 27 countries (Luxembourg, Austria, Ireland, Belgium, Italy, Denmark, Netherlands, Finland, Portugal, France, Spain, France, Finland, Portugal, France, France, Spain, France, France, France, France, France, France, Finland, Portugal, France, France, Finland, Portugal, France, France, France, France, Spain, Finland, Portugal, France, France, France, France, Spain, France, France, France, France, France, France, France, Spain Germany, Sweden, Greece, the United Kingdom, Estonia, Latvian, Lithuanian, polish, Czech, Hungarian, Slovak, Slovenian, Maltese and Cyprus) and Iceland, Norway, Portugal, Romania and Bulgaria

but as a way to rece risks, manufacturers can choose to obtain the test reports and compliance certificates of third-party testing institutions, such as CVC, in order to be better recognized by customers. CVC test report and CE certificate are widely recognized in EU.

4. EC

5. Isn't it China

6. EU countries, as long as the procts are exported to EU countries and involved, should apply for CE certification
1. Appliances burning gaseous fuels (appligas)
2. Cableway installations to carry persons
3. Low voltage electrical equipment
4. Construction procts
5. Equipment and protective systems for use in explosive environment Potentially explosive atmospheres (ATEX)
6. Explosive materials for civil uses
7. Hot water boilers burning liquid or gas fuels
8. Household Refrigerators & Freezers
9. Lift
10. Mechanical machinery
11. Marine equipment
12 Active implantable medical devices
14. In vitro diagnostic medical devices
15. Non automatic weighing instruments
16. Radio equipment & telecommunications terminal equipment (R & TTE)
17 Personal protective equipment (PPE)
18. Simple pressure vessels
19. Pressure equipment.
20. Recreational craft.
21. Toys
22. Trans European Convention rail system
23. Other...
the above procts are to be made.

7. It seems impossible to say that as long as it is a country within the scope of the European Union and authorized by the European Union directive, its CE certificate is valid. Just like the undergraate courses of Peking University and Sichuan University, they are both undergraate courses. But Peking University is more famous. You have to pay attention to command authorization. Because there are many EU directives, all license issuing agencies are only authorized by some directives, but many agencies dare to issue some CE certificates that they do not have authorization. That kind of certificate can also be used, but there are risks. I'm from Shanghai Sisi, specializing in CE and ISO. You can ask us about this.

8. "CE" mark is a kind of safety certification mark, which is regarded as the passport for manufacturers to open and enter the European market. CE stands for the unity of Europe. All procts with "CE" logo can be sold in EU member states without meeting the requirements of each member state, thus realizing the free circulation of goods within the scope of EU Member States
CE is the abbreviation of French common europeia, which means European Community in English. In fact, CE is also the & quot; of many languages in the European community; EC & quot; The abbreviation of this phrase originally used the English phrase European community to be abbreviated as EC. Later, because the European Community in French is communicate europeia, Italian is com UNITA Europea, Portuguese is com unitade europeia, Spanish is com unitade Europe and so on, EC is changed to CE
in the EU market, the "CE" mark is a compulsory certification mark. Whether it is procts proced by enterprises within the EU or procts proced in other countries, in order to circulate freely in the EU market, it is necessary to affix the "CE" mark to show that the procts comply with the basic requirements of the EU new method for technology harmonization and standardization. This is a mandatory requirement of EU law on procts.

9. CE certification is a compulsory certification of the European Union and a safety mark
institutions can be selected according to the needs of customers. It can also be evaluated according to the proct cycle and market
it can be its, SGS, Nemko, TUV of international authoritative organizations, or CNAs of domestic organizations!

10. Please note: most of the cost of these procts is service. Some service providers have lowered their prices and services. Either you can't find someone, or you can't get through the phone, or you don't have online support from the staff, it will be very troublesome. Be sure to consult for 2-3 hours first and ask clearly
