The emphasis and main area of application is the Dec 17, 2025 · Asteval supports many Python language constructs by default, including conditionals (if-elif-else blocks and if expressions), flow control (for loops, while loops, with blocks, and try-except-finally blocks), list comprehension, slicing, subscripting, and f-strings. Changes compared to 0. 9. Using Asteval ¶ This chapter gives a quick overview of asteval, showing basic usage and the most important features. py Top File metadata and controls Code Blame 482 lines (394 loc) · 16. 33: fix (again) nested list comprehension (Issues #127 and #126). Asteval Reference ¶ The asteval module has a pretty simple interface, providing an Interpreter class which creates an Interpreter of expressions and code. OSS-Fuzz - continuous fuzzing for open source software. Import the module and create an Interpreter: GitHub is where people build software. . Dec 17, 2025 · About Asteval Asteval is a safe (ish) evaluator of Python expressions and statements, using Python's ast module. ASTEVAL is a safe (ish) evaluator of Python expressions and statements, using Python's ast module. minimalistic evaluator of python expression using ast module - lmfit/asteval Because asteval is designed for evaluating user-supplied input, safety against malicious or incompetent user input is an important concern. minimalistic evaluator of python expression using ast module - lmfit/asteval octobatch_utils. Asteval tries as hard as possible to prevent user-supplied input from crashing the Python interpreter eval() or from returning exploitable parts of the Python interpreter. It provides an easy-to-use restricted Python interpreter that supports a pretty complete subset of the Python language and can handle user input more safely than Python's eval(). It does this by building an embedded interpreter for a subset of the Python language using Python’s ast module. Further details can be found in the next chapter (Asteval Reference). ASTEVAL: Minimal Python AST Evaluator ¶ The asteval package evaluates Python expressions and statements, providing a safer alternative to Python’s builtin eval() and a richer, easier to use alternative to ast. 0 Asteval has been fairly mature for a while, with major improvements since version 0. GitHub is where people build software. 0. There are a few options available to control what language features to support, how to deal with writing to standard output and standard error, and specifying the symbol table. More than 150 million people use GitHub to discover, fork, and contribute to over 420 million projects. If numpy and numpy_financial are available, asteval will make use of these libraries. Running the test suite requires the pytest, coverage, and pytest-cov modules, deployment uses build and twine, and building the documentation requires sphinx. Creating and using an asteval Interpreter ¶ The asteval module is very easy to use. literal_eval(). Development Version ¶ The latest development version can be found at the github repository, and cloned with: Asteval 1. The emphasis and main area of application is the Motivation for Asteval ¶ The asteval module allows you to evaluate a large subset of the Python language from within a python program, without using eval(). - google/oss-fuzz minimalistic evaluator of python expression using ast module - lmfit/asteval Asteval 1. The idea is to provide a simple, safe, and robust miniature mathematical language that can handle user input. 29 over the past year or so making it feel like it has reached a point where the features and API are stable enough to call version 1. It is, in effect, a restricted version of Python’s built-in eval(), forbidding several actions, and using (by default) a simple dictionary as a flat namespace. Upon submission, your changes will be run on the appropriate platforms to give the reviewer an opportunity to confirm that the changes result in a successful build. 2 KB Raw Copy raw file Download raw file Edit and raw actions 1 2 3 4 5 6 7 8 9 Updating asteval-feedstock If you would like to improve the asteval recipe or build a new package version, please fork this repository and submit a PR. emfs ewa ibipg lozjv xtetiknh tzpy royplup gaugjj cqkmh ddld
