''' 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 )

# At this point, we got two numbers and converted them into integers.

#  compare and record results

# These are several variables set to operations using rational operators between the integers. Each b1-6 is a boolean values! True or False!

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

# == and != will be particularly useful later on in the semester! More on that soon!

b5 = ( a == b )    # == is equals
b6 = ( a != b )    # != is not equals (or is different from)

#  display results

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

print()

print( a, '<=', b, ':', b3 )
print( a, '>=', b, ':', b4 )

print()

print( a, '==', b, ':', b5 )
print( a, '!=', b, ':', b6 )

print()

#  Display results

#b1 through b6 are boolean values (False and True are boolean values)
#There are only two boolean values: True and False
#There are a lot of operators that return boolean values such as <, >, <=, >==, ==, != ...

# You can see tat depending on what numbers you put in, b1-b6 will be True or False based on that.
