### How to use lift_x in python?

I am trying to use sage library in python3, but I have the following problem when I try to find points with given x-coordinate:

```
>>> from sage.all import *
>>> E = EllipticCurve('37a'); E
Elliptic Curve defined by y^2 + y = x^3 - x over Rational Field
>>> E.lift_x(1)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python3/dist-packages/sage/schemes/elliptic_curves/ell_generic.py", line 847, in lift_x
L = x.parent()
^^^^^^^^
AttributeError: 'int' object has no attribute 'parent'
```

Solution:
As John Plameri pointed out, you need to use `Integer(1)`

instead of `1`

~~.~~.
I could also have done something like: `E.lift_x(E.base_field()(1))`
