LISTS. (Muttable vs immutable) in python

Question

a=[5,6,9,8,[4,5],'willy',1,0]
a[5][2]=0
the out put shows error because strings are immutable. but LIST are mutable
So why error. can any one justify other than definition?

Answer 1

If you want to replace a letter in a word in a list, check my code. It leaves the list intact, but 'willy' becomes 'wi0ly'.

Answer 2

Try this:

a=[5,6,9,8,[4,5],'willy',1,0]
a[5]=0
print(a)

# output: [5, 6, 9, 8, [4, 5], 0, 1, 0]

Answer 3

:) thanks kesava - for future reference: very often, it's easier to understand a question when you include the current and the desired output, e. g

'willy' >> 'wi0ly'

Answer 4

It's done - check your other question, I posted the code there.

Answer 5

Remember indexing starts at 0.
Your first index [5] is actually pointing at the sixth element.
if youre trying to change the second element of the fifth element (5) in your list within a list you want it to look like:
a[4][1]=0

Answer 7

Sure, what have you got so far?

Answer 8

your question is unclear.
if you know that strings are immutable then whats the question?
if youre trying to change one character in your string you would need to convert it to a list of all of the characters or else use a str method

Answer 9

it is possible with a simple string method or re.sub...
