Python List Replacement Element

Replace direct corresponding position assignment Let's say the class is still 3 students:

>>> L = [' Adam ', ' Lisa ', ' Bart ']

Now, Bart's classmates are going to transfer, and happened to be a Paul classmate, to update the class membership list, we can first delete Bart, and then add Paul in.

Another way is to replace Bart with Paul directly:

>>> l[2] = ' paul ' >>> print LL = [' Adam ', ' Lisa ', ' Paul ']

To assign a value to an index in a list, you can replace the original element with the new element directly, and the list contains the same number of elements.

Since Bart can also index by-1, the following code can also do the same job:

>>> l[-1] = ' Paul '

L[-1] The same effect as L[-1+len (L)]
