numpy.core.defchararray.strip()

numpy.core.defchararray.strip(a, chars=None) [source]

For each element in a, return a copy with the leading and trailing characters removed.

Calls str.rstrip element-wise.

Parameters:

Parameters:	a : array-like of str or unicode chars : str or unicode, optional The `chars` argument is a string specifying the set of characters to be removed. If omitted or None, the `chars` argument defaults to removing whitespace. The `chars` argument is not a prefix or suffix; rather, all combinations of its values are stripped.
Returns:	out : ndarray Output array of str or unicode, depending on input type

a : array-like of str or unicode

chars : str or unicode, optional

The chars argument is a string specifying the set of characters to be removed. If omitted or None, the chars argument defaults to removing whitespace. The chars argument is not a prefix or suffix; rather, all combinations of its values are stripped.

Returns:

out : ndarray

Output array of str or unicode, depending on input type

Examples

>>> c = np.array(['aAaAaA', '  aA  ', 'abBABba'])
>>> c
array(['aAaAaA', '  aA  ', 'abBABba'],
    dtype='|S7')
>>> np.char.strip(c)
array(['aAaAaA', 'aA', 'abBABba'],
    dtype='|S7')
>>> np.char.strip(c, 'a') # 'a' unstripped from c[1] because whitespace leads
array(['AaAaA', '  aA  ', 'bBABb'],
    dtype='|S7')
>>> np.char.strip(c, 'A') # 'A' unstripped from c[1] because (unprinted) ws trails
array(['aAaAa', '  aA  ', 'abBABba'],
    dtype='|S7')
