Question

I was going through the Python tutorials and I decided to create a little exercise for myself with the “Lambda” tool. It’s a basic square root calculator. However, when I try to run it, it doesn’t return a number. Here’s how it looks so far.

x = int(raw_input("Enter number:"))

def power(n):
    return lambda x: x**n

sqrt = power(0.5)

sqrt(x)

Why doesn’t it work? If I’ve done made some sort of horrible mistake, please alert me. Remember, I’m a newbie so no complicated language please.

Answer 1

What do you mean by it doesn’t work? Did you just forget to do:

print sqrt(x)

instead of just

sqrt(x)

?
