代码#1:
# Python Program illustrating
# numpy.char.add() method
import numpy as np
arr1 = ['vdteteAAAa', 'AAAttttds', 'AAaxtt']
arr2 = ['1111sfdsf', '1111111sdsf2', '1111111sfsf2']
print ("\narr1 : ", arr1)
print ("\narr2 : ", arr2)
print ("\narr1 + arr2\n", np.char.add(arr1, arr2))
print ("\narr2 + arr1\n", np.char.add(arr2, arr1))
输出:
arr1 : ['vdteteAAAa', 'AAAttttds', 'AAaxtt']
arr2 : ['1111sfdsf', '1111111sdsf2', '1111111sfsf2']
arr1 + arr2
['vdteteAAAa1111sfdsf' 'AAAttttds1111111sdsf2' 'AAaxtt1111111sfsf2']
arr2 + arr1
['1111sfdsfvdteteAAAa' '1111111sdsf2AAAttttds' '1111111sfsf2AAaxtt']
代码#2:
# Python Program illustrating
# numpy.char.add() method
import numpy as np
arr1 = 'This is geeks '
arr2 = 'for geeks '
print ("\narr1 + arr2\n", np.char.add(arr1, arr2))
print ("\narr2 + arr1\n", np.char.add(arr2, arr1))
输出:
arr1 + arr2
This is geeks for geeks
arr2 + arr1
