去掉字符空格的方法

處理字符串時經常要定制化去掉無用的空格，python 中要么用存在的常規方法，或者用正則處理

1.去掉左邊空格
string = " * it is blank space test * "
print (string.lstrip())

result:
* it is blank space test *

2.去掉右邊空格
string = " * it is blank space test * "
print (string.rstrip())

result:
* it is blank space test *

3.去掉左右兩邊空格
string = " * it is blank space test * "
print (string.strip())

result:
* it is blank space test *

4.去掉所有空格
有兩種方式
eg1：調用字符串的替換方法把空格替換成空

string = " * it is blank space test * "
str_new = string.replace(" ", "")
print str_new

result:
*itisblankspacetest*
eg2：正則匹配把空格替換成空

import re

string = " * it is blank space test * "
str_new = re.sub(r"\s+", "", string)
print str_new

result:
*itisblankspacetest*
