如何让用户在测试中有2次机会得到正确的python答案

如何让用户在测试中有机会得到正确的python答案?

Answer 1

最简单的方法是使用for循环，如果它们正确，则使用break，如果它们从未正确，则可能使用else。例如:

for tries in range(2):
    print("n", "QUESTION 3:", "n", "Which level of government is responsible for Tourism?")
    print(" a) Municipal", "n", "b) Fedral", "n", "c) Provincial", "n", "d) All", "n", "e) Legislative")
    answer3 = input("Make your choice: ")
    if answer3 == "d" or answer3 == "D" :
        print("Correct!")
        break
    else:
        print("False!")
else:
    print("Out of chances!")

如果您不想每次都重印问题，只需将print调用移动到for之前。

Answer 2

def nTries(isCorrect, n = 2):
    answer = input("Make your choice: ")
    if isCorrect(answer):
        print("Correct")
    elif n == 1: 
        print("Out of tries, and incorrect")
    else:
        print("Incorrect")
        nTries(isCorrect, n - 1)

像这样设置

print("n", "QUESTION 3:", "n", "Which level of government is responsible for Tourism?")
print(" a) Municipal", "n", "b) Fedral", "n", "c) Provincial", "n", "d) All", "n", "e) Legislative")
nTries(lambda d: d.lower() == 'd')
