Hi, I want to combine these two lists.  
i.e, add List 2 items [0] comprising of 3 dates in 1st list item 0,  
similarly, add items of List 2 item [1] comprising of 6dates in 1st list item 0.  
please guide anyone.

@aneeqa_sikander Whatever you wrote doesn’t make any sense!  
Title says you want to replace items but description says you want to add items.

Is this a typo or you want to add everything to item 0 of list 1?

It’s always a good idea to attach a snip of the output you want to see along with the description.
