表示
哎哎哎:# t0]https://www . geeksforgeeks . org/num py-defchararray-multiply-in-python/
numpy.core.defchararray.multiply(arr, n) : 按元素串联字符串 n 次。
参数: arr : 阵状或弦状。 n : 【阵列式】我们要串联的次数。
按元素返回:串联字符串' n '次。
代码#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))
输出:
arr1 : ['eAAAa', 'ttttds', 'AAt']
arr2 : ['11sf', 'sdsf2', '1111f2']
arr1 : ['eAAAaeAAAa' 'ttttdsttttds' 'AAtAAt']
arr1 : ['eAAAaeAAAa' 'ttttdsttttdsttttdsttttds' 'AAtAAtAAt']
arr2 : ['11sf11sf11sf' 'sdsf2sdsf2sdsf2' '1111f21111f21111f2']
代码#2:
# Python Program illustrating
# numpy.char.multiply() method
import numpy as np
arr1 = 'This is geeks '
arr2 = 'for geeks '
print ("\narr1 : ", np.char.multiply(arr1, 2))
print ("\narr2 : ", np.char.multiply(arr2, 4))
输出:
arr1 : This is geeks
arr2 : for geeks
arr1 : This is geeks This is geeks
arr2 : for geeks for geeks for geeks for geeks
