Is this code is correct? a=2_4 b=5_0 print (a+b)

Question

a=2_4
b=5_0
print (a+b)

Answer 1

Read this, it explains why it works: https://peps.python.org/pep-0515/

Answer 2

python 3.6 and above allows to use underscores '_' as a visual separator for grouping digits in numeric literals

https://peps.python.org/pep-0515/

Answer 3

Yes valid because python provides '_' for grouping number instead of ','

Answer 6

Emerson Prado Sorry I misunderstood you 😓

Answer 7

Does the code work. Yes
Is the code correct? Yes
Why does it work? There are many uses for Underscores in Python.
However in this case.

The underscore is used to separate digits but there is no visual result.

a=2_4
b=5_0
print (a+b)

Is the same as

a=24
b=50
print (a+b)

The uses of underscore. With clear examples

But this code is running 😁

Answer 10

By the way this code is correct ☺️

Answer 11

And pls make one thing clearer: you first asked if the code is correct, then stated it is. What's your point?

Answer 12

Snehil Pandey Thanks! I just don't get why Dharmendra Pandit refuses to do such a simple job.

Answer 13

Dharmendra Pandit No one knew how to share, before we learned it

Answer 14

Snehil Pandey I mean posting the link to the code in the question. This is how the code gets visible, without one having to search one's profile, like you did.

Answer 15

Emerson Prado you can copy posted code from Q&A by selecting Copy Text from the 3-dot menu.

Answer 16

Snehil Pandey No problem

Answer 17

The code is running

Yes that is correct we can put underscore (_) for a numeric value.

If you want to write a long numeric value then best practice is use underscore between each digits and I think every language support this feature

In Java

long num = 1_2_3_4_5_6;

This is valid and will be consider as 123456

This is Java code:

public class Program
{
public static void main(String[] args) {
int num = 1_2_3_4_5_6;

System.out.println (num);
}
}

Answer 19

This syntax for writing numbers was created to separate thousandths ☺️

print(3.14_159_265_359)

You can use the format() function to print integers with spaces:

print(format(314159265359, '_'))

Did you check 2nd output in Code Playground?

It is (2, 4, 5, 0)
