ast.literal_eval (位于 ast.py )首先用 ast.parse 解析树,然后它评估丑陋的递归树函数替换树函数相当他们与他们的字面等价物。不幸的是,代码根本不可扩展,因此要将 Decimal 添加到代码中,您需要复制所有代码并重新开始。 对于稍微简单的方法,您可以使用 ast.parse 模块来解析表达式,然后使用 ast.NodeVisitor 或ast...

them to decimals, I have to convert them back to fractions (or, swap them with the text of the option) so that when the form gets submitted, I get the fraction instead of the decimal. The eval still seems to be more efficient
