How I put a √ in Python ?

Answer 1

You can use math.sqrt(x). Here you need to import math.

Or another way: √x = x^(1/2)
so in python: x**(1/2)

Answer 2

Do you mean how do you calculate it or how do you add the symbol in an output (like a print statement)?

Answer 3

[fixed]

maybe
x**(1/2) ?

Rodrigo Soriano Suso
note though that you can't do negative numbers. For that you would need complex numbers and cmath.

Answer 4

Bob_Li it is possible work with complex numbers in Python without a library. They are supported intrinsically.

x = (-9)**(1/2)
print(x)

Output:
(1.8369701987210297e-16+3j)

The real portion has a small floating point error, but that is forgivable.

Edit: changed example to show result for -9 and corrected output.

Answer 5

Rain oops, my results were the same as yours for -25. My eyes were tired, and inadvertently I copied from two different screen shots (one used -9, the other -25).

The engineering world uses j because i can be confused with the symbol for electric current.

Answer 6

Bob_Li

Yeah of course x**(1/2). I will change that. Thanks!

Answer 7

I want to mean how I can calculate it

Answer 8

Brian ,

That last letter should be j since Python decided to be weird and not use i like the rest of the world.

Also, interestingly, I got a different small error in the real portion than you did when I pasted your code into Pydroid 3, since I couldn't use the Sololearn playground while reading the discussion.

x = (-5)**(1/2)
print(x) # (3.061616997868383e-16+5j)

Answer 9

y**(1/2) use this in py for '√' of var y

Answer 10

Use the sqrt() function from math module

Answer 11

To use the radical sign (√) in Python, you can use the math module. Here's an example of how to calculate the square root of a number using the radical sign:

python
import math

number = 16
square_root = math.sqrt(number)
print("The square root of", number, "is", square_root)

When you run this code, it will output: "The square root of 16 is 4.0"

Answer 12

Thanks for all

Answer 13

.pow(number,1/2)

Answer 14

x**0.5
