tuple

A Tuple is a sequence of immutable Python objects.
Tuples are sequences, just like Lists.
The differences between tuples and lists are:
*) the same as lists except it is ordered
*) there is no equivalent in VBA

_var = ('mon','tue','wed')  
print(type(_var))         #= tuple 

Tuples cannot be changed unlike lists
Tuples use parentheses, whereas lists use square brackets.
