How to convert a tuple of string and tuples into a list of string and lists

Question

I have a created a dictionary key which is a tuple of string & tuples. The typical key looks like

("string1", ('string2','string3', 'string4'), (int1, int2, int3) )

I need to now copy the key to a list to modify string2 & int2 and reconvert it back into a new tuple which will then serve as a dictionary key to a new entry.

When I try to make a list from this tuple using

listKey = [list(i) for i in key]

I get an output that looks like

[['s','t','r','i','n','g','1'],['string2','string3','string4'],[int1, int2, int3]]

1. How can I retain the 'string1' as it was in the original dictionary key when I convert it into a list?
2. How to retain 'string1' when the modified list is converted back to tuple?

Answer 1

You may only need to call list(i) If not, you could try (("string1"),('string2', 'string3', ...) ...)

Or you could use this:

listKey = [i if isinstance(i, str) else list(i) for i in key]

Hope this helps solve your problem.
