numpy.char.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']
