Python is an object-oriented interpreted computer programming language. Python is purely free software. Python syntax is concise and clear, and one of its features is the forced use of whitespace characters as statement indentation. Python has rich and powerful libraries. It is often nicknamed the glue language, which can easily connect various modules made in other languages (especially C/C).
Python interpreter
Programming languages will involve a compiler or interpreter, using compiled languages such as C/C The program you write needs to be converted from the source file into the machine language used by the computer, and then linked by the linker to form a binary executable file. When you run this program, you can load the binary program from the hard disk into memory and run it.
Python interpretation system can be divided into: 2.x and 3.x
IDE
IDE (Integrated Development Environment, integrated development environment), currently There are many IDEs for Python, such as vs code, eclipse, atom, anaconda, IDEA, etc. I personally do not recommend using the above-mentioned IDEs. Of course, if you like these IDEs very much, you can. For developing Python, I only recommend pycharm and jupyter notebook.
Advantages of pycharm:
It has rich functions, prompts, fast speed, powerful bookmarks and jump functions, efficient debugging. Students can register to use the professional version for free...
Advantages of jupyter notebook:
Interactive debugging, switch Markdown and code at any time, take notes while writing code
Virtual environment
Python, like other programming languages, faces a migration problem. If you want to transfer a developed project to other computers or nodes or make the project into a docker image, you need to reconfigure the development environment and reinstall the project. It will be very troublesome to install the third-party tool packages used one by one. When we use the system environment, the packages installed by pip are all installed into the site-packages under the Python path. If the requirement.txt is generated All packages under site-packages will also be included. This is why a virtual environment is used. An independent environment can be created for different projects, which facilitates later transplantation.
Python virtual environment management tools mainly include the following two types:
virtualenv, pipenv

How to concatenate two lists in python 3?May 14, 2025 am 12:09 AMIn 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.
Python concatenate list stringsMay 14, 2025 am 12:08 AMUsing 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.

Python: what are the key featuresMay 14, 2025 am 12:02 AMKey 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: compiler or Interpreter?May 13, 2025 am 12:10 AMPython 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.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
