numpy.fromstring()函数– Python

numpy.fromstring()函数创建一个从字符串中的文本数据初始化的新一维数组。

Syntax : numpy.fromstring(string, dtype = float, count = -1, sep = ‘ ‘)

Parameters :

string : [str] A string that contained the data.

dtype : [data-type, optional] Data-type of the array. Default data type is float.

count : [int, optional] Number of items to read. If this is negative (the default), the count will be determined from the length of the data.

sep : [str, optional] The string separating numbers in the data.

Return : [ndarray] Return the constructed array.
