Python字符串操作实例

1、打开Python开发工具IDLE,新建‘str.py’文件，编写代码如下;str1 = '1,2,3|'li = str1.split(',')print (li)这是字符串分割，split()函数中传递分割的字符

3、使用字符串查找替换函数，代码如下：str1 = '1,2,3|'li = str1.split(',')print (str1.find('|'))s = str1.replace('|','c')print (s)

5、字符串下标截取方法和列表一样，测试代码如下：str1 = '1,2,3|'li = str1.split(',')print (str1.find('|'))s = str1.replace('|','c')print (s[1])print (s[1:])
