我写了一个程序，但是不能正常工作

Question

如何只打印（）该词典中的第一个列表？

drugs = {
    "Stimulants":["Ecstsy","Cocaine","Amphetamine"],#list only that I want to print()
    "Depressants":["Marijuana","Benzodiazepine","Heroin","Morphine"],
    "Hallucinogens":["LSD","Marijuana","Psilocybin"],
    "Opioids":["Codeine","Heroin","Methadone","Ocycodone"],
}

因为我写的时候。

if customer_0 == "Stimulants":
        print("\nFrom Stimulants we have:")
        for drugs_0 in drugs.values():
            print("\t" + str(drugs_0[0]))

它支持我

"Ecstsy",
"Marijuana",
"LSD",
"Codeine"

但是我要它打印出来。

"Ecstsy",
"Cocaine",
"Amphetamine",

Answer 1

这将起作用：

items = drugs.get("Stimulants")
    for item in items:
        print(item)

输出：

Ecstsy
Cocaine
Amphetamine
