Answer 1

You need to do ("x") only as a function arguement for example print is a function, so to print x, you must do
print("x")

When using "x" it is only a string, you can use it in string variable declarations:
x = "x"

When using only ( ) arguements are needed inside ( )
and arguements can be variables or strings

tuple(x)
tuple("x")
tuple(1)
