zipf 1.6.0

它是做什么的？

zipf包的实现简化了zipf分布的创建和操作，如和、减、乘、除、平均值、方差等静态操作。

我怎么得到它？

只需输入终端：

pip install zipf

计算距离和散度

我编写了另一个名为dictances的包，它计算离散分布（如zipf）之间的各种距离和发散。下面是一个示例：

fromzipfimportZipffromdictancesimport*a=zipf.load("my_first_zipf.json")b=zipf.load("my_second_zipf.json")euclidean(a,b)chebyshev(a,b)hamming(a,b)kullback_leibler(a,b)jensen_shannon(a,b)

使用zipf工厂创建zipf

这里有几个例子：

fromzipf.factoriesimportZipfFromListmy_factory=ZipfFromList()my_zipf=my_factory.run(["one","one","two","my","oh","my",1,2,3])print(my_zipf)'''

创建zipf的选项

有些内置选项可用，您可以通过打印来读取任何工厂对象的选项：

fromzipf.zipf.factoriesimportZipfFromListprint(ZipfFromList())'''
{
  "remove_stop_words": false, # Removes stop words (currently only Italian's)
  "minimum_count": 0, # Removes words that appear less than 'minimum_count'
  "chain_min_len": 1, # Chains up words, starting by a min of 'chain_min_len'
  "chain_max_len": 1, # and ending to a maximum of 'chain_max_len'
  "chaining_character": " ", # The character to interpose between words
  "chain_after_filter": false, # The chaining is done after filtering
  "chain_after_clean": false # The chaining is done after cleaning
