Assaignment task one doubts

join() fucntion seems to be showing an error that ;

NameError Traceback (most recent call last)
in
----> 1 join©

NameError: name ‘join’ is not defined

and if the algorithm for just to convert to cipher message is given would be helpful

The join() method is used to join all the items in a list (or any iterable datatype) into a string, using a character as separator that we specify just in front of it. It is mandatory that a string is specified infront of the join() method. We cannot execute it alone. For example to join the items in the list list1 with & as the separator, use the following code,

list1 = ["One", "Two", "Three"]
list1 = '&'.join(list1)
print(list1)

The above code will produce "One&Two&Three" as the output.

If you want to join a list of characters without any separator try using:

list1 = ''.join(list1)

Hope this helped solve your question.

about the updated task you gave me…
can you please mention what sort of process should i do?

Processing data means doing some manipulations on the data before printing the output. In the case of a string, manipulations can include converting the string to uppercase, lowercase etc.
