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 apecifiers 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('{:.2f}'.format(your_value)) 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. 312198 2042412.qx3zgy7

matted output: Caffeine levels
9.14 LAB: Input and formatted output: Caffeine levels
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
apecifiers 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('{:.2f}'.format(your_value))
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.
