我正在學(xué)習(xí)如何在 while 循環(huán)中使用 continue 語句，并將此代碼作為練習(xí)示例編寫。我希望在打印最終消息之前得到一些“本科生”、“研究生”和“博士”的回復(fù)。我可以繼續(xù)完成嗎？print("Welcome to Higher Education U. Please partake in the following roll call.")name = input("What is your name? ")level = input("Which program are you in: undergrad, grad, phd or other? ")while True: if level == 'undergrad': print(f"Hi {name}, you are one of the first undergrads.") continue elif level == 'grad': print(f"Hi {name}, you are one of the first grad students.") continue elif level == 'phd': print(f"Hi {name}, you are one of the first phd students.") continue else: print(f"Hi {name}, please consider applying to HEU!") break

while當(dāng)您到達(dá)縮進(jìn)代碼套件的末尾時，循環(huán)會自動繼續(xù)，因此您的套件無需if手動執(zhí)行。但是您需要將提示放在 中，while以便它在您進(jìn)行時不斷提示您輸入更多數(shù)據(jù)。
你的代碼可能是
print("Welcome to Higher Education U. Please partake in the following roll call.")
while True:
name = input("What is your name? ")
level = input("Which program are you in: undergrad, grad, phd or other? ")
if level == 'undergrad':
print(f"Hi {name}, you are one of the first undergrads.")
elif level == 'grad':
print(f"Hi {name}, you are one of the first grad students.")
elif level == 'phd':
print(f"Hi {name}, you are one of the first phd students.")
else:
print(f"Hi {name}, please consider applying to HEU!")
break
對于多個值，您有相同的算法，您可以將它們放入一個容器中，并且只執(zhí)行一次該算法。你想跟蹤申請者的數(shù)量，所以記錄名字的字典是有意義的。
print("Welcome to Higher Education U. Please partake in the following roll call.")
types = {"undergrad":[], "grad":[], "phd":[]}
while True:
name = input("What is your name? ")
level = input("Which program are you in: undergrad, grad, phd or other? ")
try:
normalized = level.casefold()
types[normalized].append(name)
if len(types[normalized]) < 3:
print(f"Hi {name}, you are one of the first {level}s.")
if min(len(names) for names in types.values()) > 3:
print("Classes full")
break
except KeyError:
print(f"Hi {name}, please consider applying to HEU!")
break
