numpy.fromstring¶
- numpy.fromstring(string, dtype=float, count=-1, sep='')¶
A new 1-D array initialized from raw binary or text data in a string.
Parameters: string : str
A string containing the data.
dtype : data-type, optional
The data type of the array; default: float. For binary input data, the data must be in exactly this format.
count : int, optional
Read this number of dtype elements from the data. If this is negative (the default), the count will be determined from the length of the data.
sep : str, optional
If not provided or, equivalently, the empty string, the data will be interpreted as binary data; otherwise, as ASCII text with decimal numbers. Also in this latter case, this argument is interpreted as the string separating numbers in the data; extra whitespace between elements is also ignored.
Returns: arr : ndarray
The constructed array.
Raises: ValueError
If the string is not the correct size to satisfy the requested dtype and count.
