## Issue

I have the following input:

and I want to convert it into python readable form like this `'x**2 + 2*x + 2'`

so that I can use it as an input to other functions. I have:

```
def func_parse(func):
return func.replace("^","**")
```

but this will only resolve the power part. I also want to add ‘*’ in between ‘2x’ to conform with the python syntax.

## Solution

Install `sympy`

:

```
from sympy.parsing.sympy_parser import (
parse_expr, stringify_expr, standard_transformations,
implicit_multiplication_application, convert_xor
)
transformations = (standard_transformations
+ (implicit_multiplication_application, convert_xor))
f = 'x^2 + 2x + 3'
expr = parse_expr(f, transformations=transformations)
```

Output:

```
>>> str(expr)
'x**2 + 2*x + 3'
```

**Update**

Evaluate the polynomial output with an integer value, let’s say (x =2).

```
>>> expr.evalf(subs=dict(x=2))
11.0000000000000
```
