python基础 列表和字符串

1.列表和字符串最大区别就是 列表可以改变，字符串不可以改变

列表：

welldone = [ "hutu","python","java"]
welldone[1]="php"
welldone

['hutu', 'php', 'java']

字符串：

wlldone1 = "I love biancheng "
wlldone1[1]='SHE'
wlldone1

TypeError                                 Traceback (most recent call last)
<ipython-input-37-586aab2dbbbc> in <module>()
      1 wlldone1 = "I love biancheng "
----> 2 wlldone1[1]='SHE'
      3 wlldone1

TypeError: 'str' object does not support item assignment
