這篇文章主要為大家詳細介紹了Python學習之函數及流程控制,具有一定的參考價值，感興趣的小伙伴們可以參考一下
##猜年齡大小，用戶最多猜三次
age = 50
i = 0
while i < 3:
guess_age = int(input("Please input your answer:"))
if guess_age > age:
print("too big...try again please")
elif guess_age < age:
print("too small...try again please")
else:
print("You guessed it!")
break
i += 1
if i == 3:#猜年齡，每隔三次詢問是否繼續玩
age = 50
for i in range(1,100):
guess_age = int(input("Please input your answer:"))
if guess_age > age:
print("too big...try again please")
elif guess_age < age:
print("too small...try again please")
else:
print("You guessed it !")
if i%3 == 0:
choice = input("Would you like play again? yes or no")
if choice == "yes":
continue
if choice == "no":
break
else:
continue#登入驗證，輸入錯誤三次鎖定使用者
f = open('c:/user_passwd.txt','r')
j = 3
system_user_name = str(f.readline())
system_passwd = str(f.readline())
f.close()
for i in range(1,5):
user_name = str(input("Please input your UserID:"))
password = str(input("passwd:"))
if i == 3:
s = open('c:/user_passwd.txt', 'r+')
s.write("\nlocked")
s.close()
print("This user is locked!")
break
else:
if user_name + '\n' == system_user_name and password == system_passwd:
print("Welcome" + user_name + '\n' + "Have a good time!")
break
else:
j -= 1
i += 1 print("UserID or password is wrong,Please try once again and you have " + \ str(j) + 'times choice')以上是Python學習函數及流程控制的詳細內容。更多資訊請關注PHP中文網其他相關文章！
