Variables don't have to be declared and
CAN'T BE declared!
int x
float y
There is a data type in Python, but it is
bound to the value and not to the variable.
This means, that the type of the variable may
change during execution.
i = 42 # data type is integer(implicit)
i = 42 + 0.11 # type will be changed to float
i = "fourty" # and now to a string
NOTHING
TO DECLARE
X
