Why does `a == b or c or d` always evaluate to True?
...e == "Kevin" or name == "Jon" or name == "Inbar"', setup="name='Inbar'")

Add Variables to Tuple
... can concatenate or slice them to form new tuples:
a = (1, 2, 3)
b = a + (4, 5, 6) # (1, 2, 3, 4, 5, 6)
c = b[1:] # (2, 3, 4, 5, 6)
And, of course, build them from existing values:
name = "Joe"
age = 40
location = "New York"
joe = (name, age, location)
...
Insert an element at a specific index in a list and return the updated list
... do b = a[:index] + [obj] + a[index:].
However, another way is:
a = [1, 2, 4]
b = a[:]
b.insert(2, 3)
