import math


def circle_stats(radius):
area = math.pi* 2 * radius**2
circumference = 2 * math.pi * radius
return area, circumference


a, c = circle_stats(3)
print(f"Area = {round(a, 2)}\nCircumference = {round(c, 2)}")

I know some basics of python but whenever I watch your videos, I consistently gain new insights and knowledge.

So, basically what I've understood,

"yield" is kind of like the "static" keyword which is used in c/c++.
when we say, "static int a = 5;" inside of a function & we call that function multiple times or call that function using a loop, that static variable "a" saves it's previous state in memory & performs the next tasks with it's previous state every single time function is called.

not saying they are the same. But yeah, i found it familiar.

1) first method
Below formatted variable will be displayed with 5 decimal values
formatted =

print(formatted) # output : 9.99988

And suppose we write like this
formatted =

print(formatted) # output : 10
Then it will return 10 as output.
2) using round()
In this function we will pass two parameters, first is our value or variable and second is how many decimal values we want.
Example_1:
Number = 5.375829473
print(round(Number, 2) # output : 5.36
Example_2 :
print(round(5.53627894, 2)) # output : 5.53

import math

def circle_stats(radius):
area = math.pi * radius * radius
circumference = 2 * math.pi * radius
return area, circumference

a, c = circle_stats(3)

print(f"Area: {a:.3f}, Circumference: {c:.3f}")

I have been working as a software developer since 2019. I have started coding since 2014. I have watched a lot of tutorials and read many books. But today I understood "Generator" properly. Thank you sir, you are really great. ❤❤

51:07 I have worked on some personal projects in deep learning and one use case of yield is handling huge amount of datasets where we need to fetch a batch of numbers from the datasets to perform calculation of gradients during backpropogation which is a way to optimized neural networks loss calculations

[softNandan]

Solution of 20:26 :
print(“area:”, round(a, 2), ”circumference”, round(b, 2))

[shikharpandya]

amazing video :)

TimeStamp:-
20:24
Precision upto x decimal places can be achieved by using
round(variable_name, x)

[OMKARANAVKAR]

20:20
Round method can be used to get result with n decimal places.

print "Area:", round(a, n), "Circumference:", round(c, n))

To avoid those recurring decimal in solution_04, we can use round() method to avoid those recurring decimals and can convert it to 1, 2 or any decimal place you like.
Source Code:
import math

def circle_stats(radius):
area = round(math.pi * radius ** 2, 2)
circumference = round(2 * math.pi * radius, 2)
return area, circumference

a, c = circle_stats(3)
print("Area: ", a, "Circumference: ", c)

[epslearns]

Precision can be achieved using round() function as given below:

def circle_stats(radius):
area=math.pi*radius**2

return *round(area, 2), round(circumference, 2)*

print(circle_stats(5))
(78.54, 31.42)

*Further, can we round off multiple values at once instead of doing separately for each one?*

[odecgbu]

my mind is just tuned with all your words, they just directly print into my mind i just simply run those without any errors, i think you have hacked my mind....grate full to u sir

[sheikhabdullah]

Sir, apke help se hum sab to hopeful hain... Thanks Alot!

[pranaypaul]

Kudos to you, sir, for explaining yield in such a simplified manner, as if you were explaining it to a 5-years-old.

[atharvatirkhunde]

thank you sir. I came to know about yeild for the first time. One application of args is in shoping cart.

[viditvats]

We can use the f-strings functionality. For example, if we want precision up-to 2 digits, then we can type: -

print(f"Area : {a:.2f} Circumference: {c:.2f}")

[ashishkumarbhagwani]

We do use round method for getting precise values. e.g., round(number, 2) for getting precision upto 2 digits.

Exited for the series that will based on python, Please start with Django if possible, It will be next level in your style and explanation in depth ♥
