Python通過if else和def添加

Question

所以我最初編寫這段代碼是爲了弄清楚一個人是誰，得到了一些if/elif/else語句。問題是我無法弄清楚如何讓else語句回到原來的問題，因爲這個問題只是由一個變量= raw_input語句表示的。這個想法是爲了讓我的很多朋友錯綜複雜。在用else語句修復原始問題時，我搞亂了添加部分以確定答案。我如何修復它實際計數，因爲它走了？正如你所看到的，我對編碼非常陌生。對於基本問題，我很抱歉，因爲我確信答案非常簡單。我感謝任何幫助。

from sys import exit 


Tom = 0 
Jon = 0 
Chris = 0 


def question_a(): 
    q1 = raw_input("Hello there. I am going to try to guess who you are. Would you like to play?") 

    if q1 == "yes": 
     question_b() 
    elif q1 == "no": 
     print "Well f**k you too then" 
    else: 
     print "You should follow the rules." 
    question_a() 

def question_b(): 
    print "Do you have any hair?" 

    q1 = raw_input("> ") 

    if q1== "no": 
     print "you're Karl" 
     exit(0) 


    elif q1 == "yes": 
     Tom == Tom + 1 
     Chris == Chris + 1 
     Jon == Jon + 1 
     question_c() 
    else: 
     print "You should follow the rules." 
    question_b() 

def question_c(): 
    print "Do you enjoy working on cars?" 

    q1 = raw_input("> ") 

    if q1 == "yes": 
     Chris == Chris + 1 
     Jon == Jon + 1 
     question_d() 

    elif q1 == "no": 
     Tom == Tom + 1 
     question_d() 
    else: 
     print "you should follow the rules." 
    question_c() 

def question_d(): 
    print "Do you own a husky?" 

    q1 = raw_input("> ") 

    if q1 == "no": 
     Tom == Tom + 1 
     Chris == Chris + 1  
    elif q1 == "yes": 
     Jon == Jon + 1 
    else: 
     print "Hey you, follow the rules." 
    question_d() 

    # python guess_who2.py 

    for Tom > Jon and Tom > Chris: 
     print "You're Tom" 
    for Jon > Chris and Jon > Tom: 
     print "You're Jon" 
    for Chris > Tom and Chris > Jon: 
     print "You're Chris" 
question_a() 

Answer 1

做這樣的：

from sys import exit 


def question_a(tom=0, jon=0, chris=0): 
    q = '' 
    while q not in ['yes', 'no']: 
     q = raw_input("Hello there. I am going to try to guess who you are. Would you like to play?") 

     if q == "yes": 
      question_b(tom, jon, chris) 
     elif q == "no": 
      print "Well f**k you too then" 
     else: 
      print "You should follow the rules." 


def question_b(tom=0, jon=0, chris=0): 
    print "Do you have any hair?" 

    q = '' 
    while q not in ['yes', 'no']: 
     q = raw_input("> ") 

     if q == "no": 
      print "you're Karl" 
      exit(0) 
     elif q == "yes": 
      tom = tom + 1 
      chris = chris + 1 
      jon = jon + 1 
      question_c(tom, jon, chris) 
     else: 
      print "You should follow the rules." 


def question_c(tom=0, jon=0, chris=0): 
    print "Do you enjoy working on cars?" 

    q = '' 
    while q not in ['yes', 'no']: 
     q = raw_input("> ") 

     if q == "yes": 
      chris = chris + 1 
      jon = jon + 1 
      question_d(tom, jon, chris) 

     elif q == "no": 
      tom = tom + 1 
      question_d(tom, jon, chris) 
     else: 
      print "you should follow the rules." 


def question_d(tom=0, jon=0, chris=0): 
    print "Do you own a husky?" 

    q = '' 
    while q not in ['yes', 'no']: 
     q = raw_input("> ") 

     if q == "no": 
      tom = tom + 1 
      chris = chris + 1 
     elif q == "yes": 
      jon = jon + 1 
     else: 
      print "Hey you, follow the rules." 

    # python guess_who2.py 

    if tom > jon and tom > chris: 
     print "You're tom" 
    if jon > chris and jon > tom: 
     print "You're jon" 
    if chris > tom and chris > jon: 
     print "You're chris" 

    if raw_input('Play again? (yes or no)') == 'yes': 
     question_a() 
    else: 
     print 'bye.' 

if __name__ == '__main__': 
    question_a() 

儘量先閱讀一些Python基本語法，這樣就可以輕鬆地處理if語句。

我希望你正在享受編程的世界:) 我已經對你的代碼做了一些改變，以便使它工作，我會評論它們。

from sys import exit 


Tom = 0 
Jon = 0 
Chris = 0 


def question_a(): 
    q1 = raw_input("Hello there. I am going to try to guess who you are. Would you like to play?") 

    if q1 == "yes": 
     question_b() 
    elif q1 == "no": 
     print "Well f**k you too then" 
    else: 
     print "You should follow the rules." 
     question_a() 

def question_b(): 
    global Tom, Chris, Jon 
    print "Do you have any hair?" 

    q1 = raw_input("> ") 

    if q1== "no": 
     print "you're Karl" 
     exit(0) 


    elif q1 == "yes": 
     Tom = Tom + 1 
     Chris = Chris + 1 
     Jon = Jon + 1 
     question_c() 
    else: 
     print "You should follow the rules." 
     question_b() 

def question_c(): 
    global Tom, Chris, Jon 
    print "Do you enjoy working on cars?" 

    q1 = raw_input("> ") 

    if q1 == "yes": 
     Chris = Chris + 1 
     Jon = Jon + 1 
     question_d() 

    elif q1 == "no": 
     Tom = Tom + 1 
     question_d() 
    else: 
     print "you should follow the rules." 
     question_c() 

def question_d(): 
    global Tom, Chris, Jon 
    print "Do you own a husky?" 

    q1 = raw_input("> ") 

    if q1 == "no": 
     Tom = Tom + 1 
     Chris = Chris + 1 
    elif q1 == "yes": 
     Jon = Jon + 1 
    else: 
     print "Hey you, follow the rules." 
     question_d() 

# python guess_who2.py 
question_a() 
if Tom > Jon and Tom > Chris: 
    print "You're Tom" 
elif Jon > Chris and Jon > Tom: 
    print "You're Jon" 
elif Chris > Tom and Chris > Jon: 
    print "You're Chris" 

在每一個（question_a（），question_b（）..）調用該函數應在其他語句中，以問縮進功能再次以防萬一答案是不是既不是否。

else: 
    print "You should follow the rules." 
    question_a() 

在要修改你需要指出的Python湯姆，克里斯或喬恩變量的函數，通過使用線

global Tom, Chris, Jon 

如果你想增加一個變量的點，你像這樣做：

Tom = Tom + 1 
Chris = Chris + 1 
Jon = Jon + 1 

如果你喜歡寫東西

Tom == Tom + 1 

因爲

你正在做一個布爾表達式，會給你真或假。

最後

question_a() 
if Tom > Jon and Tom > Chris: 
    print "You're Tom" 
elif Jon > Chris and Jon > Tom: 
    print "You're Jon" 
elif Chris > Tom and Chris > Jon: 
    print "You're Chris" 

我們通過調用question_a（）函數（如你已經知道）開始執行，並檢查使用如果表達的點。 對於語句用於製作循環（重複一段代碼X的次數）
