What's a good way to save these animation as video or gif ?
This is very good! A straight up for loop rather than using animate class from mpl. But could you help out how to render or export this animation? Do we have to export all the pictures and do frames/Sec manually for this??
Your Python series is my favorite. I learn from you. I look forward to future Python tutorials.
thanks :)
how to save the results in mp4 format ?
When I do the very first thing you showed here (with x_value, y_values), it plots each of the points in a separate figure in the terminal. Even though I put plt.show() after the loop. Is there any difference in how pycharm and spyder handle plt.scatter() command?
I am using PyCharm and getting the same problem. Did you figure out a solution?
If you're using jupyter notebook you can fix this by writing
%matplotlib qt
at the top of the cell.
You should be able to find something somewhere that allows you to change from inline plotting to qt (the gui library) plotting
I there a way to save the animations as gif?
Excellent video! Great job explaining this 'niche' skill
Hi, thank you for the video. I tried to follow your steps, but I got a different result. Many figures were generated to update the plot. Do you have any idea why is this happening?
x_values= [ ]
y_values= [ ]
for _ in range(100):
x_values.append(random.randint(0,100))
y_values.append(random.randint(0,100))
plt.xlim(0,100)
plt.ylim(0,100)
plt.scatter(x_values, y_values)
plt.pause(0.001)
plt.show()
Matplotlib FuncAnimation appears to use global variables. Is there a way to put the FuncAnimation code in a main() function and call it with :
if __name__ == "__main__":
main()
Thanks for another good project!
🇧🇷
i am new to python and i don't even get this , but i still love watching your videos till end
As long as you keep teaching the things they don't teach in classrooms n other tutorials, I'll keep coming back.
I love the fact you don't edit out the messy bits of programming, but instead demonstrate the process from 1st principles to working model. Most of the videos out there these days boil down to "Run this Jupyter Notebook on Collab".
thanks for your kind words! :D
7:15 Does anyone know why he used list comprehension instead of just writing the range?
I am trying to create a zodiac chart wheel and animate planets, any tips on what would be the best library to use for the animations?? ...eg. a dot( planets) going around a circle (the zodiac) thanks man
nice! i'm so doing this on my project before it's due!
^^
this is simple and helpful that I feel I need to pay for this video!. Thank you.
Hey. Id love to replicate this in my interactive VS code notebook, ipynb files, but it doesn't quite work. Has anyone found a solution?
Do you have more videos about animations im really into that it’s fun and help me to understand arrays and matrix
Your stockmarket predictor was also pretty cool
How can i install that program?
I am getting multiple charts when running this code
What to do
this very clear and helpful , thank you
How to save these as .gif files?
Cool! Is there a way to capture the animations besides using a screen recorder?
Python contour animation

i felt like you are just typing what you are reading. you were like " off course lets reshape it" lol
Is it possible to save as gif?
whats your pycharm theme?
How to save the animation ?
Why does the plt.clf() not delete the points as well?
Great video btw.
You're plotting the points in each cycle of the loop, so although you delete them a the start, you plot them again.
Can you explain the reshape command more please
your intro music is amazing
good video btw
thank you :D
Really nice video, can you please make more on these topic
How do I stop a matplotlib animation? I close it, and it reopens again!
Yes men, very nice . How to put the values of the regression line in a dataframe now ? Thnx Bro .👍👍
Thanks for the lesson, Professor. Your teaching is clear and easy to follow.

You are a great teacher.
Very nice video, thanks for sharing
Thank you for this video :]
Please give me suggestion...
How can i do this in android python ?
When i try ....
This was wrong
Why this animation work in pycharm but doesn't work in Jupiter notebook
very good and very useful
11:21 - That's a big brain trick, surrounding the _entire thing_ by `if x % 5 == 0` :D But hey, at least you've shown me that `plt.pause(...)` exists, thanks.
You were looking forward to that 50x speedup, and then... hmmm... "kind of" :D
@ 6:02 what is the purpose of x = x.reshape(-1,1); what does that do?
It reshapes the vector basically. -1 means, “hey numpy I don’t care how many rows you make but you have to make sure that I get only 1 column”. Eg: if you have matrix of shape 3,4 and you do matrix.reshape(-1,6). You will end up with a matrix of shape 2,6.
@@imdadood5705 Thank you, so to clarfiy, the -1 in (-1,1) basically subtracts 1 from the m-dimension of the original mxn-matrix?
@@georgeanton8567 Not subtract necessarily. It fixes it own dimension by looking the n dimension.
6,3.reshape(-1,1) would give 18,1
2,5.reshape(1,-1) would give 1,10
4,3.reshape(-1,6) would give 2,6
6,6.reshape(18,-1) would give 18,2
Do you see the pattern here? It just fills in appropriate value for -1 in all the instances.
If you have 5,4.reshape(-1,3) this would give you an error, because there is no way you can get 20 elements in a matrix having only three columns.
I hope I made it clear
@@imdadood5705 Wow, that cleared up a lot. Thank you for your help!
@@imdadood5705 very nice explanation, thanks!
where's your intro from?
I know that I've heard it somewhere but can't figure it out 🥺
Made it myself. The music is from the CZcams free audio library
Nice video bro 👍👍👍
Great video
You are awesome.
Your desktop has clean look👍
My jupyter notebook doesn't update the plot but creates more of it..
Good vid
Hello, can you please make a video on TCP chat room to chat with other computers on different network in python?
I think I have such a video on my channel already.
@@NeuralNine, yes sir you have a video on TCP chat room but we cannot chat with other computers on different network/LAN.
@@abeermanchanda1168 why not? Whether you use it in the internet or on localhost is not a matter of programming but of firewall settings and ip addresses
You need portforwarding
Please make a video on WhatsApp chatbot AI please make this ..
And also love you videos
Naice.
Very helpful!
nice initiative!! although, you look more focused on show how much you know Python...
Big fan Florian , can u bring some more CPP projects
which project for example?
@@NeuralNine well u r the expert , but something interesting like a password bruteforcer
Do u have a translated version of ur CPP book ? I think it's in Deutsch right ?
U don't explained many lines in the code what they do exactly unfortunately
You have a lot of audience from India
How old are you?
You ever heard of animation.FuncAnimation?
Make an pycharm clone
🎉
plt.pause() la clave
Yes i am from India 🇮🇳
first like!
first comment!

First✨✨✨♥️
Is he talking about that... hahahaha
At first, everyone did not believe in Bitcoin, then in Defi, then in NFT, and now someone really does not believe in the RJVX13 algorithm :D
Why worry about cryptocurrency quotes if there is RJVX13 algorithm?
is there really still a person who does not know about the existence of RJVX13 algorithm?
RJVX13 algorithm is my choice, i dont worry about BTC rates at all
RJVX13 algorithm is the best, there is no point in arguing with this
RJVX13 bring me 300% profit because of Tesla pump
Useless.
