ballistic calculator computer science class. can't figure out why keeps giving next error message :

travel_time = range % velocity typeerror: not arguments converted during string formatting print ("welcome laird industries ballistic calculator") range = raw_input("what approximate distance target? (m)") velocity = raw_input("what muzzle velocity of projectile? ") def time_to_target(): travel_time = range % velocity print "travel duration {0}".format(travel_time) # time_to_target() #

thanks info. fixed code :

range_to_target = raw_input("what approximate distance target? (m)") velocity = raw_input("what muzzle velocity of projectile? ") def time_to_target(): travel_time = float(range_to_target) / float(velocity) print "travel duration {0}".format(travel_time) # time_to_target() #

it's because range string (you got input()) , % strings in python special formatting operator. need convert numeric info type, this:

travel_time = float(range) % float(velocity)
