Aug 28, 2019 · Human-oriented and high-performing transpiler for Python. The main aim of transpyle is to let everyone who can code well enough in Python, benefit from modern high-performing computer hardware without need to reimplement their application in one of traditional efficient languages such as C or Fortran. Contents.
- Use list comprehensions. When you’re working in Python, loops are common. You’ve probably come across list comprehensions before. They’re a concise and speedy way to create new lists.
- Remember the built-In functions. Python comes with a lot of batteries included. You can write high-quality, efficient code, but it’s hard to beat the underlying libraries.
- Use xrange() instead of range(). Python 2 used the functions range() and xrange() to iterate over loops. The first of these functions stored all the numbers in the range in memory and got linearly large as the range did.
- Consider writing your own generator. The previous tip hints at a general pattern for optimization—namely, that it’s better to use generators where possible.

Use built-in functions and libraries: Python has a lot of built-in functions and libraries that are highly optimized and can save you a lot of time and resources.Avoid using global variables: Global variables can slow down your code, as they can be accessed from anywhere in the program. Instead, use local variables whenever possible.Use list comprehensions instead of for loops: List comprehensions are faster than for loops because they are more concise and perform the same operations in fewer lines of code.Avoid using recursion:Recursive functions can slow down your code because they take up a lot of memory. Instead, use iteration.Decorators:Decorators are a way to modify the behavior of a function or class. They are typically used to add functionality, such as logging or memoization, without changing the underlying code.Generators:Generators are a way to create iterators in Python. They allow you to iterate over large data sets without loading the entire data set into memory. This can be useful for tasks like read...Metaclasses:Metaclasses are a way to create classes that can be used to create other classes. They can be used to define custom behavior for classes, such as adding methods or properties. They can...Coroutines:Coroutines are a way to create concurrent and asynchronous code in Python. They allow you to perform multiple tasks simultaneously, and they can be used to create simple, lightweight thr...Use the built-in Python debugger (pdb): The built-in Python debugger is a powerful tool that allows you to step through your code line by line, examine variables, and set breakpoints.Use print statements: Adding print statements to your code can help you identify the source of the problem by providing a clear picture of the program’s execution flow and variable values.Use a linter: A linter is a tool that checks your code for syntax errors and potential bugs. It can help you catch errors before you run your code.Use a unit testing framework: Unit testing allows you to test small pieces of your code individually, making it easier to pinpoint the source of any errors.Use meaningful variable and function names: Use clear, descriptive names for variables and functions that accurately reflect their purpose and usage.Use whitespace and indentation: Use whitespace and indentation consistently to separate code blocks and make the structure of your code clear.Use comments: Use comments to explain the purpose of your code and any non-obvious parts of it.Keep lines short: Limit the length of your lines of code to around 80 characters, this makes it easier to read the code on different devices and screens.Python provides several advanced data structures that can be used to store and manipulate data in powerful and efficient ways. These data structures include sets, dictionaries, and tuples. 1. Sets: A set is an unordered collection of unique elements. Sets are commonly used for membership testing, removing duplicates from a list, and mathematical op...
Python has a vast ecosystem of built-in libraries that can be used for data analysis and manipulation. These libraries include: 1. NumPy: NumPy is a library for working with large arrays and matrices of numerical data. It provides functions for performing mathematical operations on these arrays, such as linear algebra, Fourier transforms, and stati...
Working with large datasets can be a challenging task, and it requires proper memory management to avoid running out of memory and to ensure the code runs efficiently. Here are some tips for working with large datasets and managing memory: 1. Use memory-efficient data structures:When working with large datasets, it’s important to use memory-efficie...
Modules and packages are a way to organize and reuse code in Python. They can be used to group related functions, classes, and variables together, and to make them available for use in other parts of the program. Here are some techniques for creating and using modules and packages: 1. Create modules: A module is a single Python file that contains P...
Object-oriented programming (OOP)is a programming paradigm that is based on the concept of objects, which are instances of classes. OOP allows you to model real-world concepts in your code, making it more organized, reusable, and maintainable. Here are some techniques for using object-oriented programming concepts in Python: 1. Create classes: In P...
Python provides a wide range of built-in functions and methods for working with strings, numbers, and other data types. Here are some advanced techniques for working with these data types: 1. String formatting: Python provides advanced string formatting techniques using the format() method and f-strings. These techniques allow you to insert dynamic...
