## 2 forms to create Square root in Python

It was always using the bookstoreÂ for a square root that is **mathÂ **then I was decided to create a square root without usingÂ bookstoresÂ we see as:

**First form utlizando bookstore math:**

very easy

**line 1** is to concern the bookstore math for the root

**line 2** to enter value by keyboard

**line 3** we applied the operation, is where the bookstore in math.sqrt works

**line 4** to print I number

okey we can improve the code ejm when they enter a negative showed error since it is only for real positives

we can create if numero>=0 and else as the second form

import math numero=input (â€œEnters I number: â€?) raiz=math.sqrt (I number) print root

**Second form all manual:)**

**line 1** is to enter a value by keyboard

**line 2** I multiply a value entered by x 1,0 to turn into real type.

**line 3 - 11** if numero>=0 since if we entered a negative ejm -9 podra not to give no result and if it did not happen to else if it does not meet condition of if and us imprimira Numero incorrec ......

**line 4** we declared p is equal to I number

**line 5** delaramos and with value 0

**line 6** while while i is different that p

**line 7** we assigned to value p to i this is only within while

**line 8** does not suck is much to write to if that reasons!

there are many ways to if that we can improve example that of multplicar *1.0 I hope that I serve do not let give to them him likes to As Programra!

numero=input (â€œEnters I number: â€?) numero=numero*1.0 if numero>=0: p=numero i=0 while i! =p: i=p p= (numero/p+p)/2 print â€œResults is: â€?, p else: print â€œWrong numberâ€?
