numpy.ndarray.setfield() function Put a value into a specified place in a field defined by a data-type. Place val into a’s field defined by dtype and beginning offset bytes into the field.
Syntax : numpy.ndarray.setfield(val, dtype, offset=0)
Parameters :
val : [object] Value to be placed in field.
dtype : [dtype object] Data-type of the field in which to place val.
offset : [int, optional] The number of bytes into the field at which to place val.Return : None.
Code #1 :
# Python program explaining # numpy.ndarray.setfield() function # importing numpy as geek import numpy as geek arr = geek.eye(4) arr.setfield(4, geek.int32) gfg = arr.getfield(geek.int32) print(gfg) |
Output :
[[4 4 4 4] [4 4 4 4] [4 4 4 4] [4 4 4 4]]
Code #2 :
# Python program explaining # numpy.ndarray.setfield() function # importing numpy as geek import numpy as geek arr = geek.eye(2) arr.setfield(2, geek.int32) gfg = arr.getfield(geek.int32) print(gfg) |
Output :
[[2 2] [2 2]]
