numpy.core.defchararray.multiply(arr, n): Concatenates strings ‘n’ times element-wise.
Parameters:
arr : array-like or string.
n : [array-like] no. of times we want to concatenate.Returns : Concatenated String ‘n’ times element-wise.
Code #1:
# Python Program illustrating # numpy.char.multiply() method import numpy as np arr1 = ['eAAAa', 'ttttds', 'AAt'] arr2 = ['11sf', 'sdsf2', '1111f2'] print ("\narr1 : ", arr1) print ("\narr2 : ", arr2) print ("\narr1 : ", np.char.multiply(arr1, 2)) # Separate multiplication print ("\narr1 : ", np.char.multiply(arr1, [2, 4, 3])) print ("\narr2 : ", np.char.multiply(arr2, 3)) |
Output:
arr1 : ['eAAAa', 'ttttds', 'AAt'] arr2 : ['11sf', 'sdsf2', '1111f2'] arr1 : ['eAAAaeAAAa' 'ttttdsttttds' 'AAtAAt'] arr1 : ['eAAAaeAAAa' 'ttttdsttttdsttttdsttttds' 'AAtAAtAAt'] arr2 : ['11sf11sf11sf' 'sdsf2sdsf2sdsf2' '1111f21111f21111f2']
Code #2:
# Python Program illustrating # numpy.char.multiply() method import numpy as np arr1 = 'This is neveropen 'arr2 = 'for neveropen ' print ("\narr1 : ", np.char.multiply(arr1, 2)) print ("\narr2 : ", np.char.multiply(arr2, 4)) |
Output:
arr1 : This is neveropen arr2 : for neveropen arr1 : This is neveropen This is neveropen arr2 : for neveropen for neveropen for neveropen for neveropen
