Calculating Square root in Python

[Haddood]

I am trying to calculate the square root of subtracting 2 numbers ...

I tried
 sqrt (x)
I get error global name sqrt not defined

I tried
 math.sqrt
I get error global name math not defined

not sure how to do it  ... help appreciated

Code: [Select]

def distance(x,y):
distance= sqrt(x-y)
return str(distance)

Hi Haddood, I tried following in VC and it works

PY.ExecString   result=({1}{3}{2})**.5

{1} is x
{2} is y
{3} is the computationally sign

here the command group (the math.xml is required in the VC payload folder)

Code: [Select]

<?xml version="1.0" encoding="utf-16"?>
<!--VoxCommando 2.0.0.5-->
<commandGroup open="True" name="math square root" enabled="True" prefix="" priority="0" requiredProcess="" description="">

  </command>
</commandGroup>
The python code will not work with negative numbers!

If you want to use math.sqrt(x)

then at the top of your python code you need to write

import math

[jitterjames]

also your distance function does not look right.

try this:

Code: [Select]

import math

def distance(x,y):
    temp = x**2 + y**2
    distance= math.sqrt(temp)
    return str(distance)

print distance(5,6)

Many thanx James ... That did the trick ... My learning curve of python is pretty flat 

Kalle thanks for the feedback, I needed to solve it within python ... I will keep you method for when i need sqrt inside VC
