任何语言都离不开字符，那就会涉及对字符的操作，尤其是脚本语言更是频繁，不管是生产环境还是面试考验都要面对字符串的操作。
python的字符串操作通过2部分的方法函数基本上就可以解决所有的字符串操作需求：
• python的字符串属性函数
• python的string模块
**1.字符串属性函数 **
系统版本：CentOS release 6.2 (Final)2.6.32-220.el6.x86_64
python版本：Python 2.6.6
字符串属性方法
字符串格式输出对齐
```
>>> str='stRINg lEArn'
>>>
>>> str.center(20) #生成20个字符长度，str排中间
' stRINg lEArn '
>>>
>>> str.ljust(20) #str左对齐
'stRINg lEArn '
>>>
>>> str.rjust(20) #str右对齐
' stRINg lEArn'
>>>
>>> str.zfill(20) #str右对齐，左边填充0
'00000000stRINg lEArn'
```
大小写转换
```
>>> str='stRINg lEArn'
>>>
>>> str.upper() #转大写
'STRING LEARN'
>>>
>>> str.lower() #转小写
'string learn'
>>>
>>> str.capitalize() #字符串首为大写，其余小写
'String learn'
>>>
>>> str.swapcase() #大小写对换
'STrinG LeaRN'
>>>
>>> str.title() #以分隔符为标记，首字符为大写，其余为小写
'String Learn'
```
字符串条件判断
```
>>> str='0123'
>>> str.isalnum() #是否全是字母和数字，并至少有一个字符
True
>>> str.isdigit() #是否全是数字，并至少有一个字符
True
>>> str='abcd'
>>> str.isalnum()
True
>>> str.isalpha() #是否全是字母，并至少有一个字符
True
>>> str.islower() #是否全是小写，当全是小写和数字一起时候，也判断为True
True
>>> str='abcd0123'
>>> str.islower() #同上
True
>>> str.isalnum()
True
>>> str=' '
>>> str.isspace() #是否全是空白字符，并至少有一个字符
True
>>> str='ABC'
>>> str.isupper() #是否全是大写，当全是大写和数字一起时候，也判断为True
True
>>> str='Abb Acc'
>>> str.istitle() #所有单词字首都是大写，标题
True
>>> str='string learn'
>>> str.startswith('str') #判断字符串以'str'开头
True
>>> str.endswith('arn') #判读字符串以'arn'结尾
True
```
字符串搜索定位与替换
```
>>> str='string lEARn'
>>>
>>> str.find('a') #查找字符串，没有则返回-1，有则返回查到到第一个匹配的索引
-1
>>> str.find('n')
4
>>> str.rfind('n') #同上，只是返回的索引是最后一次匹配的
11
>>>
>>> str.index('a') #如果没有匹配则报错
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: substring not found
>>> str.index('n') #同find类似,返回第一次匹配的索引值
4
>>> str.rindex('n') #返回最后一次匹配的索引值
11
>>>
>>> str.count('a') #字符串中匹配的次数
0
>>> str.count('n') #同上
2
>>>
>>> str.replace('EAR','ear') #匹配替换
'string learn'
>>> str.replace('n','N')
'striNg lEARN'
>>> str.replace('n','N',1)
'striNg lEARn'
>>>
>>>
>>> str.strip('n') #删除字符串首尾匹配的字符，通常用于默认删除回车符
'string lEAR'
>>> str.lstrip('n') #左匹配
'string lEARn'
>>> str.rstrip('n') #右匹配
'string lEAR'
>>>
>>> str=' tab'
>>> str.expandtabs() #把制表符转为空格
' tab'
>>> str.expandtabs(2) #指定空格数
' tab'
```
字符串编码与解码
```
>>> str='字符串学习'
>>> str
'xe5xadx97xe7xacxa6xe4xb8xb2xe5xadxa6xe4xb9xa0'
>>>
>>> str.decode('utf-8') #解码过程，将utf-8解码为unicode
u'u5b57u7b26u4e32u5b66u4e60'
>>> str.decode('utf-8').encode('gbk') #编码过程，将unicode编码为gbk
'xd7xd6xb7xfbxb4xaexd1xa7xcfxb0'
>>> str.decode('utf-8').encode('utf-8') #将unicode编码为utf-8
'xe5xadx97xe7xacxa6xe4xb8xb2xe5xadxa6xe4xb9xa0'
```
字符串分割变换
```
>>> str='Learn string'
>>> '-'.join(str)
'L-e-a-r-n- -s-t-r-i-n-g'
>>> l1=['Learn','string']
>>> '-'.join(l1)
'Learn-string'
>>>
>>> str.split('n')
['Lear', ' stri', 'g']
>>> str.split('n',1)
['Lear', ' string']
>>> str.rsplit('n',1)
['Learn stri', 'g']
>>>
>>> str.splitlines()
['Learn string']
>>>
>>> str.partition('n')
('Lear', 'n', ' string')
>>> str.rpartition('n')
('Learn stri', 'n', 'g')
```
