Python--if 、while、for

###if判断
# age_wj = 28
# age = int(input('Please enter my age:'))
#
# if age == age_wj:
#     print('Yes! you are right')
# elif age < age_wj:
#     print('No! too small try again')
# else:
#     print('No! too big try again')


###while循环
# age_wj = 28
# count = 0
# while count < 3:
#     age = int(input('Please enter my age:'))
#     if age == age_wj:
#         print('Yes! you are right')
#         break
#     elif age < age_wj:
#         print('No! too small, please try again')
#     else:
#         print('No! too big, please try again')
#     count += 1
# else:
#     print("You don't have a chance")

# age_wj = 28
# count = 0
# while count < 3:
#     age = int(input('Please enter my age:'))
#     if age == age_wj:
#         print('Yes! you are right')
#         break
#     elif age < age_wj:
#         print('No! too small, please try again')
#     else:
#         print('No! too big, please try again')
#     count += 1
#     if count == 3:
#         count_try = input("Whether or not to continue...")
#         if count_try != 'n':
#             count = 0
# else:
#     print("You don't have a chance")


###for循环
# age_wj = 28
# count = 0
# for i in range(3):
#     age = int(input('Please enter my age:'))
#     if age == age_wj:
#         print('Yes! you are right')
#         break
#     elif age < age_wj:
#         print('No! too small, please try again')
#     else:
#         print('No! too big, please try again')
#     count += 1
# else:
#     print("You don't have a chance")

# for i in range(10):
#     if i<5:
#         print("loop", i)
#     if i==4:
#         print("呵呵...")
#     else:
#         continue
