Back to the point, we should not go to study now seems to be useless and really good things?
My answer is: if you really have the power and are willing to invest in yourself, I think it is necessary.
1, this extra study will make your weekends full.

There's something Python can do, but Java can't do.
Why do you want to learn Python as a Web?
Reply content:Java Python Programmer:
Stage One: How the hell did Java get so much pain?
Stage Two: Python Dafa good, import antigravity
Stage Three: Dynamic type of momentary cool,
the damn types can make you spit blood, often write code 1-2 hours, type conversion takes 1-2 hours to try
Python Full StackAdvantages
Simple conversion
The software is very small
Code Open Source
Disadvantages
Because it is open source, the code cannot be hidden, even if it can be hidden, it is easy to decompile
Open source, a lot of Ides instead of the original Python
Python world is known for the machine learning library to count Scikit-learn. This library has many advantages. Easy to use, interface abstraction is very good, and document support is really moving. In this article, we can encapsulate many of these machine learning algorithms, and then perform a one-time test to facilitate analysis and optimization. Of course, for the specific algorithm, the super-paramet

In this case, the non-fee curriculum masks the entry to the advanced stages, and the instructor is fundamentally from BAT's and it elite, a big benefit for it's small white or career-savvy people who want to be advanced. At the same time, there are many courses within the group that are relevant to python, such as "Python opens up the situation", "
