html#recipes
）用於貨幣值的格式化、某些三角學函式，以及常見問題
（Frequently Asked Questions，FAQ）。
gmpy2 模組
gmpy2
模組是以 C 編寫的一個擴充功能（extension），它支援 GMP、MPFR
與 MPC 程式庫，以擴充和加速 Python 的能力，進行多精度（multiple-
precision）的算術（即算術中所涉及的數字之精確度只受限於可用的記憶
體量）。
gmpy2
的主要開發分支支援具有執行緒安全性的情境（thread-safe
contexts）。你可以從 PyPI（
https://pypi.python.org/pypi/gmpy2
）下載並安裝
gmpy2
。
陣列處理
你能以串列（涵蓋於前面的「串列」）表示陣列（arrays），也能以
array
標準程式庫模組（涵蓋於前面的「array 模組」）來表示。你能以迴圈、
索引或切片動作、串列概括式（list comprehensions）、迭代器、產生器、
genexps（全都涵蓋於第 3 章）、內建的
map
、
reduce
與
filter
（全都涵蓋
於前面的「內建函式」），以及像是
itertools
（涵蓋於前面的「itertools 模
組」）的標準程式庫模組來操作陣列。如果你只需要輕量化的一維（one-
dimensional）陣列，使用
array ...
