''' Purpose: introduce relational operators

#  get two numbers from user

print()

sa = input( 'Enter number: ' )
sb = input( 'Enter number: ' )

print()

# convert inputs to integer

a = int( sa )
b = int( sb )

#  compare and record results

b1 = ( a < b )     # < is less than
b2 = ( a > b )     # > is greater than

b3 = ( a <= b )    # <= is less than or equal to
b4 = ( a >= b )    # >= is greater than or equal to

b5 = ( a == b )    # == is equals because = is assignment
b6 = ( a != b )    # != is not equals...tells us whether two things are different

#  display results

print( a, '< ', b, ':', b1 )
print( a, '> ', b, ':', b2 )

# Python has ints, floats, and what are known as boolean values
# there are only two boolean values: True and False
# there are a lot of operators that return boolean values such as <, >, <=, >=, ==, !=, and, or
