07-numpy字符串操作

import numpy as np
print(np.char.add(["hello"],["baby"]))#['hellobaby']
print(np.char.add(["hello","A"],["baby","B"]))#['hellobaby' 'AB']
print(np.char.multiply("nimei",3))#多个字符串叠加成一个字符串
print(np.char.center("*",20,fillchar="_"))#字符串填充
print(np.char.capitalize("nimei"))#返回字符串开头大写
print(np.char.title("nimeititle,hao are you"))#每个字母开头大写
print(np.char.lower("ABC"))
print(np.char.upper("abc"))
print(np.char.splitlines("hellp \n 123213"))#按行切割
print(np.char.split("hellp \n 123213",sep="\n"))#按sep切割
print(np.char.strip(" A A A "))#取出首尾空格
print(np.char.str_len("ABCD E"))#求长度
print(np.char.join(":","ABC"))#每个字母拼接：
print(np.char.join(":",["ABC","EFG"]))#每个字符串每个字母拼接：
print(np.char.join([":","@"],["ABC,EFG"]))#对应拼接
print(np.char.replace("hello A","A","B"))#A替换成B
print(np.char.encode("富强","utf-8"))#编码
print(np.char.decode(b'\xe5\xaf\x8c\xe5\xbc\xba',"utf-8"))#解码
