UCALC等同 [英] UCALC equivalent
问题描述
http://www.ucalc.com/mathparser/index.html
有一个很棒的图书馆名为UCALC，它允许你设置一个
表达式并对其进行评估
例如你通过调用UCALC中的一个函数来定义一个表达式
然后使用各种值来调用它，例如：
参见本页
http://www.ucalc.com/mathparser /sample6.html
速度非常快。我已经在VB中使用它了，当时有很多数字
正在处理。
是否有Python等价物。
我看了numPy和SciPy的网站（刚刚浏览过）看起来好像没有我想要的东西。
任何指针？

There is a great library called UCALC which allows you to set up an
expression and evaluate it
for e.g. you an define an expression by calling a function in UCALC
then call it with various values of x
for e.g. see this page
http://www.ucalc.com/mathparser/sample6.html
It is very fast. I have used it in VB when there is lot of number
crunching to be done.
Is there a Python equivalent.
I looked at numPy and SciPy sites (just skimmed through) did''nt seem
to have what I wanted.
Any pointers?

推荐答案
Python内置了eval功能，并不需要< br $>
a库。

Dark Cowherd写道：
Python has built in eval function and doesn''t require
a library.

你在开玩笑吗？仔细阅读原帖。
o.p.正在寻找一个评估数学表达式的库
并且可以从python代码中调用。

Are you kidding? Read the original post a little more closely. The
o.p. is looking for a library that evaluates mathematical expressions
and is callable from python code.
