1、
>>> a = ["aa","bb","cc","dd","ee"] >>> temp = a[1] ## 引入變量 >>> temp 'bb'
>>> a[1] = a[3] >>> a ['aa', 'dd', 'cc', 'dd', 'ee'] >>> a[3] = temp >>> a ['aa', 'dd', 'cc', 'bb', 'ee']
2、
>>> a = ["aa","bb","cc","dd","ee"] >>> a ['aa', 'bb', 'cc', 'dd', 'ee'] >>> a[1],a[3] = a[3],a[1] ## 直接交換 >>> a ['aa', 'dd', 'cc', 'bb', 'ee']
