10 Ways to Speed Up Your Python Code ⚡️ 1. List Comprehensions numbers = [x**2 for x in range(100000) if x % 2 == 0] instead of numbers
= []
for x in range(100000):
    if x % 2 == 0: 
        numbers.append(x**2)

2. Use the Built-In Functions Many of Python’s built-in functions are written in C, which makes them much faster than a pure python solution. 3. Function Calls Are Expensive Function calls are expensive in Python. While it is often good practice to separate code into functions, there are times where you should be cautious about calling functions from inside of a loop. It is better to iterate inside a function than to iterate and call a function each iteration. 4. Lazy Module Importing If you want to use the time.sleep() function in your code, you don't necessarily need to import the entire time package. Instead, you can just do from time import sleep and avoid the overhead of loading basically everything. 5. Take Advantage of Numpy Numpy is a highly optimized library built with C. It is almost always faster to offload complex math to Numpy rather than relying on the Python interpreter. 6. Try Multiprocessing Multiprocessing can bring large performance increases to a Python script, but it can be difficult to implement properly compared to other methods mentioned in this post. 7. Be Careful with Bulky Libraries One of the advantages Python has over other programming languages is the rich selection of third-party libraries available to developers. But, what we may not always consider is the size of the library we are using as a dependency, which could actually decrease the performance of your Python code. 8. Avoid Global Variables Python is slightly faster at retrieving local variables than global ones. It is simply best to avoid global variables when possible. 9. Try Multiple Solutions Being able to solve a problem in multiple ways is nice. But, there is often a solution that is faster than the rest and sometimes it comes down to just using a different method or data structure. 10. Think About Your Data Structures Searching a dictionary or set is insanely fast, but lists take time proportional to the length of the list. However, sets and dictionaries do not maintain order. If you care about the order of your data, you can’t make use of dictionaries or sets. 🔗Source #tips

Create Beautiful Diagrams with Python 📊 🔸Diagrams is a Python library which lets you draw the cloud system architecture in Python code. It was born for prototyping a new system architecture design without any design tools. You can also describe or visualize the existing system architecture as well. As you can see from the example above, it's extremely simple to create your own customized diagram. See more examples here. ⚙️Installation
pip install diagrams

Complex Numbers in Python 🐍 Most general-purpose programming languages have either no support or limited support for complex numbers. Python is a rare exception because it comes with complex numbers built in. The quickest way to define a complex number in Python is by typing its literal directly in the source code: >>> z1 = 1 + 2j You can also use a built-in Python function, complex(). It accepts two numeric parameters. The first one represents the real part, while the second one represents the imaginary part denoted with the letter j in the literal you saw in the example above:
>>> z2 = complex(1, 2)
>>> z1 == z2
True

To get the real and imaginary parts of a complex number in Python, you can reach for the corresponding .real and .imag attributes:
>>> z2.imag
2.0
Note that both properties are read-only because complex numbers are immutable, so trying to assign a new value to either of them will fail. 🔗In-depth tutorial on complex numbers by RealPython #tutorial #complex

Assert Statements in Python ♦️Python’s assert statement is a debugging aid that tests a condition. If the condition is true, it does nothing and your program just continues to execute. But if the assert condition evaluates to false, it raises an AssertionError exception with an optional error message. ♦️The goal of using assertions is to let developers find the likely root cause of a bug more quickly. An assertion error should never be raised unless there’s a bug in your program. They’re not intended to signal expected error conditions, like “file not found”, where a user can take corrective action or just try again. #tips

How to handle messy CSV files 🐍 🔸CleverCSV is a Python package for detecting the dialect of CSV files with high accuracy. It is modeled on the way in which a human would determine the dialect: by looking for patterns that result in a regular tabular structure with “clean data” in the cells (such as numbers, dates, etc.). The package is designed to help a data scientist with messy CSV files. It also provides a handy command line tool that can standardize a messy file or generate Python code to import it. ⚙️Installation pip install clevercsv[full] 🔗GitHub 🔗Docs 🔗[Research] Wrangling Messy CSV Files by Detecting Row and TypePatterns #clevercsv #csv

Top 5 Python GUI Libraries 🖥 A Graphical User Interface (GUI) is the first thing your user sees and interacts with when he opens your application or website. A user interface usually includes a host of visual elements like icons, buttons, graphics, displayed text, and several other forms of input, like checkbox, text input boxes, and such. The goal behind this post is to help you to find the right framework for building interactive GUIs with the several GUI frameworks Python has to offer. ▪️PyQt5 The PyQt package is built around the Qt framework, which is a cross-platform framework used for creating numerous applications for various platforms. It also offers the QtGui and the QtDesigner module, which provide numerous visual elements that the developer can implement with a simple drag and drop. ▪️Tkinter Tkinter was created to equip modern developers with a standard interface to the Tk GUI toolkit with its Python bindings. In Tkinter’s world, most of the visual elements that we’re familiar with are called widgets, and each of these widgets offers a different level of customizability. ▪️Kivy Kivy is an open-source GUI framework for building some of the most intuitive user interfaces encompassing multi-touch applications that implement Natural User Interface (NUI). With Kivy, interface designers can code once and deploy to multiple platforms. ▪️wxPython wxPython allows Python developers to create native user interfaces that add zero additional overhead to the application. The cross-platform capabilities of wxPython allow deployment to platforms like Windows, Mac OS, Linux, and Unix-based systems with little to no modifications. ▪️PyGUI PyGUI is a graphical application cross-platform framework for Unix, Macintosh and Windows. Compared to some other GUI frameworks, PyGUI is by far the simplest and lightweight of them all. PyGUI inserts very less code between the GUI platform and Python application, hence the display of the application usually displays the natural GUI of the platform. #materials #gui
