#  get two numbers from user

# convert inputs to integer

a = int( sa )

#  compare and record results
# We are setting all these b_ variables to a boolean!
# A boolean is a logical value (True/False)
# We can set a variable equal to a boolean by giving it a
# comparison (like a < b) and True/False will be stored in the boolean
# based on what the comparison is (True/False)
# Numbers are compared as normal but for strings (alphanumeric
# characters), a < z so "ab">"aa" and "abc" > "abb"
b1 = ( a < b )     # < is less than
# Python will evaluate the expression to True / False
# The value of the expression (the comparison you're making)
# will be True/False (evaluated to True/False) and the value
# True/False will be stored as a result of that comparison
# into the variable!
# if ( condition / expression ):
    # condition/expression will be True/False
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
b6 = ( a != b )    # != is not equals

#  display results
