Python 3.4：while循環不循環

Question

如果用戶的猜測大於或小於隨機生成的值，Python循環不想循環回來。它要麼退出循環，要麼創建一個無限循環。我哪裏錯了？對不起，如果我的格式糟糕，第一次海報。

import random 

correct = random.randint(1, 100) 
tries = 1 
inputcheck = True 
print("Hey there! I am thinking of a numer between 1 and 100!") 
while inputcheck: 
    guess = input("Try to guess the number! ") 
    #here is where we need to make the try statement 
    try: 
     guess = int(guess) 
    except ValueError: 
     print("That isn't a number!") 
     continue 
    if 0 <= guess <= 100: 
     inputcheck = False 
    else: 
     print("Choose a number in the range!") 
     continue 
    if guess == correct: 
     print("You got it!") 
     print("It took you {} tries!".format(tries)) 
     inputcheck = False 
    if guess > correct: 
     print("You guessed too high!") 
     tries = tries + 1 
    if guess < correct: 
     print("You guessed too low!") 
     tries = tries + 1 

    if tries >= 7: 
     print("Sorry, you only have 7 guesses...") 
     keepGoing = False 

Answer 1

問題是與這一行：

if 0 <= guess <= 100: 
    inputcheck = False 

這將終止每當用戶輸入0和100之間的數字環路可以改寫該部分爲：

if not 0 <= guess <= 100: 
    print("Choose a number in the range!") 
    continue 

Answer 2

正確的代碼如下：

import random 

correct = random.randint(1, 100) 
tries = 1 
inputcheck = True 
print("Hey there! I am thinking of a numer between 1 and 100!") 
while inputcheck: 
    guess = input("Try to guess the number! ") 
    #here is where we need to make the try statement 
    try: 
     guess = int(guess) 
    except ValueError: 
     print("That isn't a number!") 
     continue 
    if 0 > guess or guess > 100: 
     print("Choose a number in the range!") 
     continue 
    if guess == correct: 
     print("You got it!") 
     print("It took you {} tries!".format(tries)) 
     inputcheck = False 
    if guess > correct: 
     print("You guessed too high!") 
     tries = tries + 1 
    if guess < correct: 
     print("You guessed too low!") 
     tries = tries + 1 
    if tries > 7: 
     print("Sorry, you only have 7 guesses...") 
     inputcheck = False 

這裏的問題是，當guess的值介於0和100之間時，您將inputcheck設置爲False。將此值更改爲False，並且循環已退出，因爲此時不再是True。

此外，你應該改變而循環的最後if情況，因爲現在這個修復無限期運行的情況下：

if tries > 7: 
    print("Sorry, you only have 7 guesses...") 
    inputcheck = False
