problem using pyeval_expression

[akbarza]

hi
i found the below code in a net page( i do not know the exact address of it):

1 2 3

from pyeval_expression import Expression expr=Expression(" 53 * -4 +2 * 3 ") print(expr.result())

after running the code in idle, the below error appeared:

Error:
Traceback (most recent call last):
  File "D:\14020412_enteghal\akb_python\akb_py_projects\vscode_workspace\expr_test.py", line 1, in <module>
    from pyeval_expression import Expression
ModuleNotFoundError: No module named 'pyeval_expression'

then in cmd, I wrote:
C:\WINDOWS\system32>pip install pyeval_expression
and the result is:

Output:
ERROR: Could not find a version that satisfies the requirement pyeval_expression (from versions: none)
ERROR: No matching distribution found for pyeval_expression

My Python version is Python 3.11.5 .
what can I do to fix the problem?
thanks

I search for pyeval_expression and find nothing. Where did you find a reference to this thing?

Code is not publish on PyPi,code is just a repo on GitHub.
Usage:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

Maybe this one? Name is similar but not exact.

On PyPi.

pip install py-expression-eval

hi
I used cmd for the command: pip install py-expression-eval
and then I changed the code to:

1 2 3

from py_expression_eval import Expression expr=Expression(" 53 * -4 +2 * 3 ") print(expr.result())

but the below error was shown:

Error:
Traceback (most recent call last):
  File "D:\14020412_enteghal\akb_python\akb_py_projects\py_expression_eval_example.py", line 7, in <module>
    expr=Expression(" 53 * -4 +2 * 3 ")
TypeError: Expression.__init__() missing 3 required positional arguments: 'ops1', 'ops2', and 'functions'

Then you most follow the Doc py-expression-eval.

1 2 3 4 5 6

>>> from py_expression_eval import Parser >>> >>> parser = Parser() >>> p = parser.parse('53 * (-4) +2 * 3') >>> p.evaluate({}) -206

Or Simpleeval.

1 2 3 4

>>> from simpleeval import simple_eval >>> >>> simple_eval(" 53 * -4 +2 * 3 ") -206
