First: Python basic grammar stage. The learning difficulty of Python basic grammar stage is relatively small, but if the computer foundation is weak, you need to do more experiments and establish your own programming ideas as soon as possible. In the process of learning Python, we should not only do more experiments, but also pay attention to communicate with technical experts and make full use of Internet resources.

Second: machine learning stage. Machine learning is not only one of the two main ways of big data analysis, but also one of the six research directions in the field of artificial intelligence, so learning machine learning is still more important. After mastering Python language, you can directly learn some classic algorithms in the field of machine learning, and then complete the process of algorithm implementation and algorithm training through Python language, and then gradually master the steps of machine learning.

Third: the stage of big data platform. Learning big data knowledge must be inseparable from learning big data platform. Novices can learn Hadoop and Spark. Although the content is relatively more, there are also many learning cases to refer to, so you won't encounter too many learning obstacles. For those with strong learning ability, they can also teach themselves.

Only by paying attention to the foundation can we go further. Many people think that learning programming only needs the steps I just mentioned, learning grammar, writing simple demo, then learning advanced features, and finally starting to do projects. But this is only the most junior programmer. Without this language, they may have nothing.

Without the support of computer foundation, they don't understand the principle of computer network, why should they consider the principles of network programming, DNS and load balancing, and operating system, so they can't understand the root cause of server failure, can't troubleshoot, and can't understand data structures and algorithms, so they don't understand why some programs should be written like this, and some collection classes should be designed like this.

Paying attention to the foundation is what every programmer should do. Without a foundation, everything else is a castle in the air, and the foundation is not firm. You won't even have the confidence to talk about technology, let alone architecture and business scenarios.
