# determine chrysanthemum color given an input soil pH level
#       acidic soil produces pink chrysanthemums
#   non-acidic soil produces blue chrysanthemums

# acidity threshold

ACIDIC_THRESHOLD = 7.0     # samples less than threshold are acidic

# get soil pH level of interst
reply = input( 'Enter soil pH level: ' )

pH = float( reply )

print( )

# analyze and report effect on chrysanthemums
#   if acidic print 'pink';  otherwise print 'blue'
if ( pH < ACIDIC_THRESHOLD ):
    print( 'pink' )
else:
    print( 'blue' )

# all done
