  Pyrex
Pyrex lets you write code that mixes Python and C data types any way you want, and compiles it into a C extension for Python.
Pyrex requires Python 2.3 or later, both to run the Pyrex compiler and to use the generated extension modules.
Discussion of Pyrex is also welcome on the Python newsgroup, comp.lang.python.

  Pyrex: Why Pyrex Bowls "Explode" - Consumerist
Pyrex bowls were originally made of something called borosilicate glass, which is very resistant to thermal shock.
I exploded a pyrex bowl on a stovetop as a child in the mid-80s.
Pyrex says it is safe to move from the freezer to the oven because it is. It takes time for the glass to heat up so it is not a sudden temp change.

 PYREX
Pyrex was considered to be a distinct advantage over plate glass for one overriding reason, a lower coefficient of expansion.
Pyrex tubing could be subjected to common glass blowing techniques without fear of cracking and test tubes and flasks made of Pyrex could be subjected to extreme heat and quenching without shattering - wonderful.
The one advantage that can be credited to Pyrex for the use of small as well as large telescope mirrors is the fact that it is substantially harder than plate glass or optical glass and is therefore more resistant to scratching and very minor surface imperfections that can cause scattering.

  Pyrex takes the heat of the kitchen for generations   (Site not responding. Last check: )
Pyrex Portables, another newer product, are the standard 9-by-13-inch glass baking dishes, but they come with a plastic lid, a carrying case and a microwaveable hot-pack that allows cooks to keep their dishes warm on the way to a potluck.
Pyrex was used as the glass in the windows of the Apollo and Gemini spacecraft in the 1960s and '70s.
Pyrex used to come in a variety of designs -- homemakers of varying ages remember brightly-colored Pyrex bowls with flowers, hens, snowflakes, grape clusters and other patterns that were the fashion of the day.

 Pyrex Explosion
Even Pyrex can shatter if there is a large enough temperature difference at a small enough contact point.
Thermal Stress Although Pyrex is designed to go in and out of the oven, it still has to deal with thermal stress and fatigue.
On the contrary, Pyrex is some of the best stuff for high temperature cooking.

 可爱的 Python: Pyrex 扩展并加速 Python 应用程序   (Site not responding. Last check: )
有些东西似乎不对。速度提高几个百分比和 Pyrex 主页(以及很多 Pyrex 用户)那样提高 40 倍有很大的差距。现在应该来看一下 这个 Python
我也编写了一个与实际的 Python 函数相同的函数,基本来说,只是去掉这些声明。运行这个函数的 Pyrex 和 Python 两个版本,以及 Psyco 化的 Python 版本,所需要的时间如下:
Pyrex 有很多功能都实现得非常好。对于在循环中使用简单的数字或字符数据的代码来说,Pyrex 的加速效果非常明显,在最佳情况中,可能会是 50 倍。如果 Python 应用程序碰到数值函数方面的明显瓶颈,为这些函数创建一个 Pyrex 版本就非常有意义。但是在有些情况中,您会发现要想获得明显的提升是非常有限的。花费大部分时间在库函数调用上的代码不会像那些简单循环任务一样使用 Pyrex 可以获得明显的加速。而且,在很多情况中,增加两行代码启用 Psyco 就可以达到将 Python 代码中度修改为 Pyrex 所能达到的加速效果。虽然 Pyrex 代码很容易编写,但是您必须 编写 这些代码,这一点与 Psyco 不同。

 Pyrex Summary
Pyrex is created by adding boron to the traditional glassmaker's "frit" of silicate sand, soda, and ground lime.
Pyrex begins to soften around 821 °C (1510 °F); at this temperature, the viscosity of type 7740 Pyrex is 10
Pyrex's refractory properties and physical strength make it ideal for use in laboratories, where it is used to make high-durability glass lab equipment, such as beakers and test tubes.

 Visitors Culinary Toy Purchases - Bakeware - Pyrex
Pyrex glass is especially desirable, as it's constructed to be durable and is safe to use in the oven, microwave, freezer, and dishwasher.
Pyrex has been making quality glass products for the better part of a century--this company pioneered heat- and cold-resistant glassware--so when it comes to glass, they know whereof they speak.
Since 1915, Corning Pyrex cookware has been a vital part of every kitchen, and because it is safe in the oven, freezer, and microwave, it is even more versatile today than when it was first introduced.

 Charming Python: Pyrex extends and speeds Python apps
Pyrex itself gives you access to all the C-level constructs that are most important for speed, while saving you from all the C gotchas of memory allocation and deallocation, pointer arithmetic, prototypes, and so on.
To use Pyrex, you do need to change a bit more in your code (but only just a bit), and you also need to have a C compiler available and properly configured on the system on which you generate the Pyrex module.
This Pyrex function still looks quite a bit easier to read than the corresponding C function would, but it is certainly more complicated than was my naively elegant pure-Python version.

 Pagan Origins of the Christ Myth > The End > pyrex victory
A Pyrex victory is named for a Greek general who, congratulated on a costly victory against the Romans, or someone, replied unforgettably: "Three more wins like that, and we're whipped." Or something.
Pyrex wasn't his real name, by the way.
Absent thee from felicity a while; wise general Pyrex didn't have us in mind, maybe, but he had us bang to rights.
