A half-life is the amount of time it takes for a substance or entity to fall to half its original value. Caffeine has a half-life of about 6 hours in humans. Given caffeine amount (in mg) as input, output the caffeine level after 6, 12, and 24 hours. Use a string formatting expression with conversion specifiers to output the caffeine amount as floating-point numbers. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: print (f' {your_value:.2f}') Ex: If the input is: 100 the output is: After 6 hours: 50.00 mg After 12 hours: 25.00 mg After 24 hours: 6.25 mg Note: A cup of coffee has about 100 mg. A soda has about 40 mg. An "energy" drink (a misnomer) has between 100 mg and 200 mg. 461710.3116374.qx3zqy7 LAB ACTIVITY 3.14.1: LAB: Input and formatted output: Caffeine levels 1 caffeine_mg = float(input()) 2 3 main.py 0/10 Load default template...
