The following equations estimate the calories burned when exercising (source): men: calories = ( (age x 0.2017) — (weight x 0.09036) + (heart rate x 0.6309) — 55.0969 ) x time / 4.184 women: calories = ( (age x 0.074) — (weight x 0.05741) + (heart rate x 0.4472) — 20.4022 ) x time / 4.184 write a program using inputs age (years), weight (pounds), heart rate (beats per minute), and time (minutes), respectively. output calories burned for men and women. output each floating-point value with two digits after the decimal point, which can be achieved as follows: print('men: %0.2f calories' % calories_man) python
