Input and formatted output for python
问题
I understand that you want the code to be translated. Here is the translated code in Chinese:
def caffeineLevel(caffeine_mg):
half_life = 6
hours = [6, 12, 24]
for h in hours:
caffLvl = caffeine_mg * (0.5)**(h / half_life)
print(f"经过 {h} 小时: {caffLvl:.2f}mg")
If you have any further questions or need assistance with this code, please let me know.
英文:
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.
def caffeineLevel(caffeine_mg):
half_life = 6
hours = [6, 12, 24]
for h in hours:
caffLvl = caffeine_mg * (0.5)**(h / half_life)
print(f"After {h} hours: {caffLvl:.2f}mg")
I tried the code above and it did not work.

你定义了函数caffeineLevel()。尝试像caffeineLevel(100)这样的语句，它应该产生一个输出。
英文:
You defined the function caffeineLevel(). Try a statement like caffeineLevel(100) and it should churn out an output.

我刚刚运行了它，它有效。你只是忘记调用你定义的函数。
def caffeineLevel(caffeine_mg):
half_life = 6
hours = [6, 12, 24]
for h in hours:
caffLvl = caffeine_mg * (0.5)**(h / half_life)
print(f"After {h} hours: {caffLvl:.2f}mg")
caffeineLevel(1000)
英文:
I just ran it and it works. You just forgot to call the function that you defined.
