The syntax for when to use a () and when to use [] still throws me a
curve.
() is tuples which are immutable which means that the items can't be
changed. [] is list which means that each item can be changed.
Tuples are useful because they can be used as keys in dictionaries and
are guarantied not to change. Lists are useful because they can be
updated.
This is wrong, commas define tuples.
type mytest.py
a = 1, 2
print(type(a))
c:\Users\Mark\MyPython>mytest.py
<class 'tuple'>
