At present, java is a technical language with a high market share. Learning java can basically cope with more than 80% of the work on the market.
Python is a rapidly developing technology, and it is easy to get started. There are still a lot of work requirements, but python is simple to get started and difficult to go deep.
Web front-end is a career with a wide range of employment. Any interface you see needs front-end implementation, which is relatively simple to learn. And front-end learning is more interesting than other technical learning.
The entry threshold for software testing is also relatively low, and the demand of enterprises is still relatively high. A whole set of projects need products, development, testing and operation and maintenance, so the market demand is still relatively high.
If you want to enter the IT industry, you can choose according to the direction you want to engage in. If you want to work deeply in this industry, it is recommended to learn java. If you want to make your job more interesting and learn the front end, although python is recommended, I think python is easy to get started. The main core of python is in three directions: web crawler, data analysis and artificial intelligence, and it will be more difficult to learn Python deeply.
