Demystifying Python Basics: A Beginner's Guide
python is a popular and versatile high-level programming language. With its easy-to-understand syntax, rich library and modules, and strong community support, Python has become an ideal choice for both beginners and experienced developers.
type of data
- Integer (int): Integer value, no decimal part.
- Floating point number (float): Numeric value with decimal part.
- Boolean value (bool): True or False.
- String (str): Text consisting of a sequence of characters.
- List (list): A set of ordered elements, which can be any data type.
- Tuple (tuple): An immutable collection of ordered elements, which can be any data type.
- Dictionary (dict): A collection of key-value pairs, where the key is unique and the value can be of any data type.
Operator
- Arithmetic operators: (addition), - (subtraction), * (multiplication), / (division), % (remainder).
- Comparison operators: == (equal), != (not equal), (greater than), = (greater than or equal to).
- Logical operators: and (and), or (or), not (not).
Control flow
- Conditional statements: if, elif, else.
- Loop statement: for, while.
- Function: A reusable block of code that performs a specific task.
- Class: A blueprint used to define objects, including data members and methods.
- Module: A reusable unit of code containing functions, classes, and variables.
Standard Library
The Python standard library provides a series of built-in functions, classes, and modules for handling a variety of common tasks:
- Operating System: Interacts with Operating System.
- File processing: Reading and writing files.
- JSON: Interact with JSON data.
- Regular Expressions: Match and manipulate text.
- Scientific Computing: NumPy, SciPy and other libraries.
Community Support

Is Python executed line by line?May 10, 2025 am 12:03 AMPython is not strictly line-by-line execution, but is optimized and conditional execution based on the interpreter mechanism. The interpreter converts the code to bytecode, executed by the PVM, and may precompile constant expressions or optimize loops. Understanding these mechanisms helps optimize code and improve efficiency.
What are the alternatives to concatenate two lists in Python?May 09, 2025 am 12:16 AMThere are many methods to connect two lists in Python: 1. Use operators, which are simple but inefficient in large lists; 2. Use extend method, which is efficient but will modify the original list; 3. Use the = operator, which is both efficient and readable; 4. Use itertools.chain function, which is memory efficient but requires additional import; 5. Use list parsing, which is elegant but may be too complex. The selection method should be based on the code context and requirements.
Python: Efficient Ways to Merge Two ListsMay 09, 2025 am 12:15 AMThere are many ways to merge Python lists: 1. Use operators, which are simple but not memory efficient for large lists; 2. Use extend method, which is efficient but will modify the original list; 3. Use itertools.chain, which is suitable for large data sets; 4. Use * operator, merge small to medium-sized lists in one line of code; 5. Use numpy.concatenate, which is suitable for large data sets and scenarios with high performance requirements; 6. Use append method, which is suitable for small lists but is inefficient. When selecting a method, you need to consider the list size and application scenarios.

Python: For and While Loops, the most complete guideMay 09, 2025 am 12:05 AMIn Python, a for loop is used to traverse iterable objects, and a while loop is used to perform operations repeatedly when the condition is satisfied. 1) For loop example: traverse the list and print the elements. 2) While loop example: guess the number game until you guess it right. Mastering cycle principles and optimization techniques can improve code efficiency and reliability.
Python concatenate lists into a stringMay 09, 2025 am 12:02 AMTo concatenate a list into a string, using the join() method in Python is the best choice. 1) Use the join() method to concatenate the list elements into a string, such as ''.join(my_list). 2) For a list containing numbers, convert map(str, numbers) into a string before concatenating. 3) You can use generator expressions for complex formatting, such as ','.join(f'({fruit})'forfruitinfruits). 4) When processing mixed data types, use map(str, mixed_list) to ensure that all elements can be converted into strings. 5) For large lists, use ''.join(large_li

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),

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.
