arr2 : array-like or string.返回: Concatenates String.
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：
