去掉所有空格：

有两种方式

eg1：调用字符串的替换方法把空格替换成空

string = " * it is blank space test * "

str_new = string.replace(" ", "")

print str_new

result:

*itisblankspacetest*

eg2：正则匹配把空格替换成空

import re

string = " * it is blank space test * "

str_new = re.sub(r"\s+", "", string)

print str_new

result:

*itisblankspacetest*
