for的循环语句for(String s : args)这个格式是foreach的形式，表示取出数组args[]中的每一个元素，就是循环一次就依次取出一个元素赋值给s，知道取完为止java中的foreach也是用for表示具体语法分两种：第一种-数组for(type var : arr) {//循环体}示例（这里以List为例）：List<String> list = n...

bitarray: efficient arrays of booleans This library provides an object type which efficiently represents an array of booleans. Bitarrays are sequence types and behave very much like usual lists. Eight bits are represented by one byte in a contiguous block of memory. The user can select between...
astype(np.int32) Out[43]: array([ 3, -1, -2, 0, 12, 10], dtype=int32) If you have an array of strings representing numbers, you can use astype to convert them to numeric form: In [44]: numeric_strings = np.array(['1.25', '-9.6', '42'], dtype=np.string_) In [45]...
