PYTHON CODE ONLY:
Given the string, s, and the list, lst, associate the variable contains with True if every string in lst appears in s (and False otherwise). Thus, given the string Hello world and the list ["H", "wor", "o w"], contains would be associated with True.

lst=["H", "wor", "o w"]

s='Hello world'

contains = True

for i in range (0, len(lst)):

 if not lst[i] in s:

   contains = False

   break

Explanation:

Above code works fine if you make sure that identation is correct.

yes we can change both the color of the value of a cell as well as background color of a cell at the same time .

as we know that excel sheet consists of columns and rows.

and intersection of column and row is called cell.

we can change color of the cell and background of the cell at the same time.

hence the statement that

can a person change color of the cell and background of the cell at the same time is true.
