If you already "from module import function as aliias" don't try to use function name

Question

from math import sqrt as square_root
print(square_root(100))
print(sqrt(100))
Will cause error
from math import sqrt as square_root
print(square_root(100))
print(sqrt(100))

Answer 1

It does not cause any error that I'm aware of.

from math import sqrt as square_root
print(square_root(16))
# Output: 4.0

The only error I'll see is your attempt to use the 'sqrt' as a function, but that doesn't exist, since it is under the variable name 'square_root".

If you're planning on using more than one function from a module, it is better to just import the whole thing. Otherwise, I'm not sure what error you're talking about?
