检测到键后，多次执行一个循环

Question

我有代码：

while True:
     if keyboard.is_pressed("i"):
          print(usr)

因此，当我运行程序的其余部分并进入代码时，代码可行！它检测到我在键盘上按“我”。但是，它多次打印字典usr。无论如何我可以解决这个问题吗？我尝试了break关键字，但随后它停止了整个程序。请帮我！对不起，如果这不是最好的问题？我不太确定我关心整个声誉的事情，但是，我想确保自己撰写正确的帖子。

整个代码：

# My very own first game
# Completely made by Cyb3rst0rm

import keyboard

print('Hello, welcome to Terminal Adventure!')
q0 = input("What is your name? ") # q0, name
print('Nice to meet you ' + q0 + '!')

questions = ["Do you like fruit? Yes or No ", 
"Do you like vegetables? Yes or No ", 
"Do you play any sports? Yes or No ",
"Do you like chocolate? Yes or No ",
"What is your age? ", # index 4, question 5, q5, age
"What is your race? ", # index 5, question 6, q6, race
"What is your gender? ", # index 6, question 7, q7, gender
]

user = {}

def infoCall(usr):
    while True:
        if keyboard.is_pressed("i"):
            print(usr)

def mainLoop():
    q1 = input(questions[0])
    if q1 == 'Yes':
        q1 = input("What fruit do you like? ")
        print("Cool! I can't eat " + q1 + " because I'm not a human.")
    elif q1 == 'No':
        print("Haha, you're not alone in that! ")
    q2 = input(questions[1])
    if q2 == 'No':
        print("Me neither! They're disgusting!")
    elif q2 == 'Yes':
        print("Weirdo, haha")
        q2 = input("What vegetable do you like? ")
        print("I'm not so sure about that one.")
    q3 = input(questions[2])
    if q3 == 'Yes':
        q3 = input("What sport? ")
        print(q3 + " sounds fun!")
    if q3 == 'No':
        print("Hey we're both couch-potatoes!")
    q4 = input(questions[3])
    if q4 == "No":
        q4 = input("Chocolate's amazing! Why don't you like it? ")
        print("I don't agree with that, I'm sorry, chocolate is amazing.")
    elif q4 == "Yes":
        q4 = input("Hey me too! What type of chocolate do you like? ")
        print("Cool! I like dark chocolate.")
    q5 = input(questions[4])
    q6 = input(questions[5])
    q7 = input(questions[6])
    user = {"name": q0, "age": q5, "race": q6, "gender": q7}
    print("Here is the information you entered!")
    print(user)
    infoCall(user)

def askBegin():
    begin = input("Shall we begin the game? Yes or No ")
    if begin == 'Yes':
        mainLoop()
    elif begin == 'No':
        quit
    else:
        print('Not an accepted answer! Please try again.')
        askBegin()

askBegin()

如果我正确理解，则应在与print（）的相同级别上添加break。这种行为的原因可能是print比is_pressed快得多。

def infoCall(usr):
    while True:
        if keyboard.is_pressed("i"):
            print(usr)
            break

如果您希望它永远继续下去，则仅在按下“我”时打印用户，请尝试以下操作：

def infoCall(usr):
    while True:
        keyboard.wait("i"):
        print(usr)
