Job (title will do):
1. The while loop output 1234568910
n = 1
while n < 11:
if n == 7:

continue
else:
print(n)
n += 1
2. All numbers 1-100 and seek
sum = 0
n = 1
while n <= 100:
sum += n
n += 1
print(sum)
3. The outputs of all the odd-numbered 1-100
n = 1
while n <= 100:
if n % 2 == 1:

else:
n += 1
4. Output all even within 1-100
n = 1
while n <= 100:
if n % 2 != 1:
print(n)
n += 1
else:
n += 1
The request and all numbers 1-2 + 3-4 + 5 ... 99
sum1 = 0

7: Guess the age of the game
要求：
允许用户最多尝试3次，3次都没猜对的话，就直接退出，如果猜对了，打印恭喜信息并退出= Age '1111'
Chance = 0
the while Chance <. 3:
guess_age = INPUT ( 'Instantly guess:')
IF guess_age == Age:
Print ( 'regressed guessed')

the else:
Print ( 'wrong Guess')
Chance +. 1 =
8: Guess the age of an upgraded version of the game (Optional Problem)
Requirements:
allows the user to try up to three times
per attempt three times, if you have not guessed, asked whether the user would like to continue playing, if the answer Y or y, then allowed to continue to guess three times, this back and forth, if the answer N or n, to exit the program
how guessed will exit
Age = '1111'
Yes = [ 'Y', 'the Y']
NO = [ 'n-', 'N']
Tag = True
Chance = 0
the while Tag:
guess_age = input ( 'Take a guess:')
IF guess_age == Age:
Print ( 'Congratulations, you guessed it')
Tag = False
the else:
Print ( 'the wrong')
Chance + 1 =
IF Chance == 3:
answer the iNPUT = ( 'Please continue to enter y / Y, exit enter the n-/ N:')
IF answer in yes:
Tag = True
Chance = 0
elif answer in NO:
( '! Welcome to the next use') Print
Tag False =
the else:
Print ( 'end program input error!')
Tag = False
