Synopsis
putmask(a,mask,values)
a must be a contiguous array.
mask is a sequence with the same length as
a
.flat.
values is a sequence of values that can be
converted to a’s type
code (if shorter than mask,
values is repeated as needed). Each
element of a corresponding to a true item
in mask is replaced by the corresponding
item in values. putmask
