How to teach yourself Python programming? There are a bunch of Python tutorials but you feel like you don’t know where to start? I think this should be a problem that many Python beginners are struggling with.
What I want to share with you today is how to teach yourself Python programming. Learning this is really not something everyone is good at. Some people have a lot of Python. Tutorials but feel like they don’t know where to start. Some people rely on a bunch of Python tutorials to get started. This is the gap! So what should we do for those who have taken a bunch of Python tutorials but are at a loss?
Let’s take a look. How did other seniors solve the same problem?
My learning experience sharing
Not only learning Python, you have to practice anything you learn. If you only read books, firstly, you will not be able to remember them; secondly, after reading for a long time, you will lose motivation and cannot stand anymore.
Share my own experience.
My exposure to Python started with crawlers (blushing, I will never write xjb again). At that time, I only knew how to write according to the online tutorials, relying on my own C/C foundation to forcibly understand the meaning of Python code. If it were an exam, I would even copy down my student ID number.
Later I discovered that Python and C are completely two different things, and Python is not simple either. It contains very interesting syntax. Since I haven't read the book systematically, I don't understand some details of Python at all. I can only check it on the spot when writing the code and piece it together.
Later, I felt that my foundation was unstable and I couldn’t continue writing, so I tried to read Liao Xuefeng’s blog and Python core programming. I finished reading Liao Da's book and skipped some chapters, which are very basic. I didn’t finish the core programming book because I felt that many things were basically useless. It was just running examples, which was very boring. Later, I gave up after reading half of the book.
At this time, my Python level is to forcefully use c thinking to program, and then use Python to translate. They are all simple statements and have absolutely nothing to do with python. I guess it’s not even considered entry-level at this point. Later, I slowly found some small projects to practice and gradually improved myself
Must learn in the project
For example, I want to extract 100 personnel information from excel or txt Find the phone number of a girl younger than 25 years old.
First think about how to operate, and then use python to implement it. Then when you are finished, you will have a certain understanding of using python to manipulate text and assemble data structures. .
The next step is how to store this data in the database, and then use python to check the information of the person you want. At this time, you have an understanding of python's database operations
Next First step, how to add and delete personnel information in the database through python
Then think about how to add a UI to implement the operation, whether to use web or python graphics library
Finally, think about how to package this program Turn it into an executable program instead of a script
Through such a small exercise, you can know how to master the basics of python
Only by learning in a project can you learn to program.
Of course, it is actually difficult for beginners to get started because they don’t even understand the principles of programming, let alone follow up on projects. If you really want to get into this industry, then having a teacher lead you through practical projects is the best way.

In Python 3, two lists can be connected through a variety of methods: 1) Use operator, which is suitable for small lists, but is inefficient for large lists; 2) Use extend method, which is suitable for large lists, with high memory efficiency, but will modify the original list; 3) Use * operator, which is suitable for merging multiple lists, without modifying the original list; 4) Use itertools.chain, which is suitable for large data sets, with high memory efficiency.

Using the join() method is the most efficient way to connect strings from lists in Python. 1) Use the join() method to be efficient and easy to read. 2) The cycle uses operators inefficiently for large lists. 3) The combination of list comprehension and join() is suitable for scenarios that require conversion. 4) The reduce() method is suitable for other types of reductions, but is inefficient for string concatenation. The complete sentence ends.

Key features of Python include: 1. The syntax is concise and easy to understand, suitable for beginners; 2. Dynamic type system, improving development speed; 3. Rich standard library, supporting multiple tasks; 4. Strong community and ecosystem, providing extensive support; 5. Interpretation, suitable for scripting and rapid prototyping; 6. Multi-paradigm support, suitable for various programming styles.

Python is an interpreted language, but it also includes the compilation process. 1) Python code is first compiled into bytecode. 2) Bytecode is interpreted and executed by Python virtual machine. 3) This hybrid mechanism makes Python both flexible and efficient, but not as fast as a fully compiled language.
