fromstring
(string, dtype=float, count=-1, sep='')¶ A new 1-D array initialized from 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
The string separating numbers in the data; extra whitespace between elements is also ignored.
Deprecated since version 1.14: If this argument is not provided,
fromstring
falls back on the behaviour offrombuffer
after encoding unicode string inputs as either utf-8 (python 3), or the default encoding (python 2).Returns: arr : ndarray
The constructed array.
Raises: ValueError
If the string is not the correct size to satisfy the requested
dtype
and count.See also

>>> np.fromstring('1 2', dtype=int, sep=' ') array([1, 2]) >>> np.fromstring('1, 2', dtype=int, sep=',') array([1, 2])
