website = 'http://www.python.org'
website[18:] = 'com'
错误说:
'str' object does not support item assignment.
为什么这段代码不合法？
请您参考如下方法:
因为字符串是不可变的。这样做:
>>> website = 'http://www.python.org'
>>> website = website[:18] + 'com' # build a new string, reassign variable website
>>> website
'http://www.python.com'
