y /= 3 – answer y = y / 3
what are some different types of variables? - answer Integers, Floating-Point, Strings,
Booleans
what is an integer? - answer whole numbers, no decimals/fractions
what are floating-point numbers? - answer numbers with a decimal point
what is Boolean? - answer single value either true or false

false is assumed to have the value 0
x=3
y=4
print(str(x) + ':' + str(y)) - answer3:4

== - answer equal to
!= - answer inequality
a = 10
b = 10
, c = 20
d = ((a>b) and (b<=c)) or (not((((c<=a+b) and (a==10)) or ((b==10) and c!=10))))
