Ultimate Guide to NumPy Arrays - VERY DETAILED TUTORIAL for beginners!

Күн бұрын

In this tutorial, we will learn about NumPy arrays in great detail! 🤓
NumPy is one of the most popular Python libraries and just as it sounds - it deals with numbers!
An array, on the other hand, is a collection of items of the same type and it's the data structure that NumPy uses.
This video will give you the tools and demos to understand how NumPy manages data and how it approaches memory consumption.
We will explore different functions and methods to:
⭐ create N-dimensional arrays
⭐ reshape arrays
⭐ sort arrays with different algorithms
⭐ filter and manipulate array values
The goal of this Ultimate Guide (and all the future Ultimate Guides I'll be filming for other libraries) - is to cover a HUGE part of the NumPy documentation. It's meant for all the folks who learn by example rather than by reading dry text and hopefully this will take your NumPy skills to an expert level! 🥼🥼🥼

I worked with numpy arrays for some time, i'm still not sure what's the difference between int and uint

@PythonSimplified 2 жыл бұрын

This is a great question Sinisa!! 😀 ⭐ int reserves one bit to store whether the integer is negative or positive. ⭐ uint, on the other hand, stands for "unsigned integer" so it doesn't track whether the integer is negative or not. It is assumed to be non-negative, for example: the speed of a motorcycle cannot be negative, therefore it makes more sense to store it as a uint. So in the case of uint, there is no reserved bit that tracks the sign (sign means either - or +) so it's free to store other data. In other words, while both int and uint take up the exact same number of bits - unit has the potential to convey larger numbers. An extremally abstract example: int is +0001011 (we have 7 available slots to store data, the first bit is reserved) uint is 00001011 (we have 8 available slots to store data, the first bit is not reserved) I hope it helps! 😊

My task at hand: Array manipulation and processing, for tracking stars in a telescope/camera view.

@PythonSimplified 2 жыл бұрын

Live camera feed involves some kind of visualization library rather than NumPy, checkout my OpenCV + ipWebCam tutorial: kzfaq.info/get/bejne/i8pzhsyLt57ciY0.html You'll be able to use your mobile phone to track the stars. On top of that, you'll need to involve some Machine Learning techniques so that your computer can interoperate the image. I don't have any object detection tutorials yet, but I have many image classification ones in my AI + ML playlist: kzfaq.info/sun/PLqXS1b2lRpYTpUIEu3oxfhhTuBXmMPppA And you can probably speed up processes by using Yolov5 (pre trained neural network) to do that. I hope it helps and good luck! 😊

I recoded one of my projects from python lists to numpy recently and it brought the execution time down from about 25 minutes to less than a minute. Most of that minute is io operations in reading and writing the data to by database, the rest is probably one operation where I can't apply arithmetic directly to the array and I have to loop through each element individually, and I can't use multiprocessing or multithreading because I need the answer to the previous item as the starting point for the next item - at least for that individual section of data. I can split the data into about 15000 sections and work on individual sections in parallel. I am dealing with about 10 million rows of data each with 6 columns.

We will then convert the numeric data into an image file (using PILLOW or CV2, haven't decided yet) So we will have a visual example of what numbers mean in terms colours and images 😀 So definitely stay tunned! 😉

Yo yo Udbhav! 😁 Lists are an abstract data structure in many programming languages (abstract = theoretical). They're simply defined as a collection of items. In order to implement them we usually have 2 options: 1. We can implement them as an array. (A collection of items OF THE SAME KIND). 2. We can implement them as a linked-list. Where we work with something called "pointers" to store where the item is located in memory (yes, it's just as complex as it sounds hahahaha 😅 that's why I try to avoid it whenever possible) Now the beauty of Python, is that it actually has the ability to implement lists! it can store different types of data on the exact same list, for example: my_list = ["apple", True, 1, 0.5, "cat"] This is not something we can do with c++ as lists cannot be implemented as is. So before we can store a collection of items in c++, we need to make sure that all the items have the exact same data type. Now, even though we have the ability to implement lists in Python - by doing so we waste a lot of memory resources. So our code runs - but it uses more memory than we potentially can use. By using arrays in Python, we solve this problem as we restrict the number of memory bits each array item can use. So if we are dealing with an array of boolean values, we can select the np.bool8 data type which only takes up 1 byte (8 bits). While by default, if we are not being specific with the data type - each of the array items would take up 64 or 32 bits - which is a HUGE waste of resources! 😃 Check out this video at 04:27 where I explain it a bit differently 😉 I hope it helps!

tbf numpy feels like a circumvention of pythons horrible dynamic versatility for the specific case of numerics, like a hollow connection to the power of more static languages such as C/C#/C++.

I absolutely agree with @@richi1235 ! 😊 You can start with the basic programming concepts such as: variables, data types, control flow operations (for loops, while loops, conditional statements, functions) then move on with object oriented programming (classes) and then with external libraries (NumPy, Pandas, etc.) I have a really nice vlog where I explain my road map of learning Python, you can check it out here 😁: kzfaq.info/get/bejne/rax1dpqHx72miqM.html Additionally, I recently had an interview on Eric Willsons' podcast, where we discuss this roadmap in more detail. Here's the community post where I shared it: kzfaq.infoUgkxoKgTyBWEMjKrz6HIncB5uxmrQiWEGXu4 And the best part is, while you use Python to learn these programming concepts - you can actually apply them on almost any other programming language!!! I find that starting with Python is very easy and extra intuitive, but once you are comfortable with everything you've learned - switching to Javascript, C#, C++, etc will be incredibly simple! 😀😀😀 Best of luck on your programming journey! 💪💪💪

Do you really need to learn numpy arrays if you know pandas well? Not sure I unde how they intersect. Thanks

@PythonSimplified 2 жыл бұрын

NumPy deals with numeric data structures and mathematical operations, Pandas deals with organizing all kinds of data into tables, manipulating it and visualizing it. They can definitely intersect if you're working on a database full of numeric data, or if your plotting your arrays in a graph but otherwise - they have very different purposes so you can't really replace one with another 😀 Checkout my Pandas basics tutorial to see the difference: kzfaq.info/get/bejne/sLRie9iSm9WteWQ.html I hope it helps! 😁

with the eye array, what if I wanted a range of k values, for example k=-1,0,1? great video by the way, way better than my shitty lecturer

Можно ли транспонировать 2х мерный архив?

@PythonSimplified 2 жыл бұрын

I believe you can do it with my_array.reshape((*a flipped shape to the original archive*)) but I don't know if I fully understood the question 😊 I must admit that my Russian knowledge doesn't include complex words, I left Crimea when I was 6 years old so my vocabulary can't really handle words like "транспонировать" hahaha 😅😅😅
