string模板(template)参考: http://blog.csdn.net/caroline_wendy/article/details/27054263
string.Template()内添加替换的字符, 使用"$"符号, 或 在字符串内, 使用"${}"; 调用时使用string.substitute(dict)函数.
可以通过继承"string.Template", 覆盖变量delimiter(定界符)和idpattern(替换格式), 定制不同形式的模板.
代码:
# -*- coding: utf-8 -*- ‘‘‘ Created on 2014.6.5 @author: Administrator @edition : python 3.3.0, eclipse pydev ‘‘‘ import string template_text = ‘‘‘ Delimiter : %% Replaced : %with_underscore Ingored : %notunderscored ‘‘‘ d = {‘with_underscore‘ : ‘replaced‘, ‘notunderscored‘ : ‘not replaced‘} class MyTemplate(string.Template): delimiter = ‘%‘ idpattern = ‘[a-z]+_[a-z]+‘ t = MyTemplate(template_text) print(‘Modified ID pattern: ‘) print(t.safe_substitute(d))
Modified ID pattern: Delimiter : % Replaced : replaced Ingored : %notunderscored
