add()

此函数执行元素字符串连接。

import numpy as np 
print 'Concatenate two strings:' 
print np.char.add(['hello'],[' xyz']) 
print '\n'
print 'Concatenation example:' 
print np.char.add(['hello', 'hi'],[' abc', ' xyz'])

其产出如下 -

Concatenate two strings:
['hello xyz']
Concatenation example:
['hello abc' 'hi xyz']
