pls I want to write a function that can compute for the sqrt root of
any number.bt it not working pls help.
Whenever describing an error, be precise. In this particular case, we
have some sourcecode (which is good!) but what is still missing is what
exactly you see when running that code (output and error messages) and
what you expected instead.
from math import sqrt
def squareroot(self):
x = sqrt(y)
print x
In this very case, I also wonder if the tutorial you are learning from
assumes Python 2 while you are using Python 3. This is important,
because "print" is a special statement in Python 2 but a normal function
in Python 3.
That said, I see two errors here:
1. "self": This is customary used when you have a class function that
takes an instance of that class. This instance is then the first
parameter and called "self". Python doesn't enforce this, but you should
adhere to this convention to avoid confusion. Since you are not writing
a class, don't name this parameter "self".
2. There is no "y" in that code. I guess that if you renamed your "self"
to "y", you would get what you wanted.
Good luck and welcome to Python!
