General computer training ranges from 3,000 yuan to 30,000 yuan, as follows: 1, training time is 3 months and 5 months, computer office software and computer basic knowledge training, and the tuition fee is about 3,000-5,000 yuan; 2.java, web, Python, Big Data and other majors, the training fee for six months is about10000-25000; 3. The training time is one year and a half, and the training fees for junior and senior high school students such as software development and network engineering are about 10000-30000 (tuition, living expenses, accommodation and meals, etc.). Generally speaking, the time of computer training is three months, half a year, one year and one and a half years, which are the four common computer training times.

For example, recent college students who have a foundation usually train computer majors such as java, web front-end and Python, and the time is mostly 6 months. However, 0-based high school graduates, their training majors are generally software development, network engineering, java and other courses, and the time is more than one year.
