所以，我正在學(xué)習(xí) Python 3。我嘗試編寫(xiě)一個(gè)腳本，讓你猜一個(gè)從 1 到 20 的數(shù)字?，F(xiàn)在我知道這不是最好的方法，但是當(dāng)我運(yùn)行代碼時(shí)，它會(huì)進(jìn)入無(wú)限環(huán)形。是什么原因造成的？我做錯(cuò)了什么？我的問(wèn)題的目的是了解我的錯(cuò)誤以及導(dǎo)致錯(cuò)誤的過(guò)程。感謝你們。# Defining the function inside which the verification happensdef guesst(secretNumber, inputNumber): numberOfGuesses = 0 if inputNumber >= 1 and inputNumber <= 20: while inputNumber: if inputNumber > secretNumber: numberOfGuesses += 1 print('Your guess is too high.') elif inputNumber < secretNumber: numberOfGuesses += 1 print('Your guess is too low.') elif inputNumber == secretNumber: print('Your guess is correct, congratulations!

閱讀這兩行：
if inputNumber >= 1 and inputNumber <= 20: while inputNumber:
循環(huán)體while不會(huì)改變inputNumber。如果它在 1..10 或 12..20 范圍內(nèi)，則您的循環(huán)等于while True:并且它將永遠(yuǎn)運(yùn)行。您可能希望在if循環(huán)內(nèi)部進(jìn)行測(cè)試，并且您肯定希望在您返回評(píng)估循環(huán)條件時(shí)更改值，例如通過(guò)input設(shè)置新值。

嘗試這個(gè)
def guesst(secretNumber):
numberOfGuesses = 0
while True:
inputNumber = int(input('I\'m thinking of a number between 1 and 20, try to guess which one: '))
if inputNumber > secretNumber:
numberOfGuesses += 1
print('Your guess is too high.')
elif inputNumber < secretNumber:
numberOfGuesses += 1
print('Your guess is too low.')
elif inputNumber == secretNumber:
print('Your guess is correct, congratulations! You\'ve my number in ', numberOfGuesses, 'guesses.')
break
else:
print('Please enter a number between 1 and 20')
# Defining the variables used by the function
snum = 11
guesst(snum)
當(dāng) while 循環(huán)重復(fù)時(shí)，您需要再次收集用戶的輸入，因此您的輸入語(yǔ)句應(yīng)該在 while 循環(huán)中，而不是在函數(shù)之外。
您的 if 語(yǔ)句也應(yīng)該在 while 循環(huán)內(nèi)。

變量 inputNumber 不會(huì)在 while 循環(huán)中更新。
嘗試添加：
inputNumber = int(input("please try again"))或者大意是允許用戶在下一次迭代之前更新他們的猜測(cè)。
