1、使用while循环输出 1 2 3 4 5 6 8 9 10
count = 0
while count < 10:
count += 1
if count == 7:
continue
print(count)
运行结果为：1 2 3 4 5 6 8 9 10
2、求1-100的所有数的和
a = 0
for i in range(1,101):
a = a+i
print(a)
运行结果为：5050
3、输出1-100内的所有奇数
n = 1
while n<101:
if n % 2 == 0:
n = n + 1
else:
print(n)
n = n + 1
4、输出1-100内的所有偶数
n = 1
while n<101:
if n % 2 == 0:
print(n,end=" ")
n = n + 1
else:
n = n + 1
5、求1-2+3-4+5、、、99的所有数的和
num = 0
for i in range(100):
if i % 2 == 0:
num = num - i
else:
num = num + i
print(num)
6、猜年龄游戏
、、、python
要求：
1、允许用户最多尝试3次
2、每尝试3次后，如果还没猜对，就问用户是否还想继续玩，如果回答Y或y，就继续让其猜3次，以此往复，如果回答N或你，就退出程序
3、如果猜对了，就直接退出
age = 10
count = 0
numb = 0
tag = True
Y = ['Y','y']
N = ['N','n']
while tag:
count = 0
while count<3:
num_inp = input("please give your age>>:")
num_inp = int(num_inp)
if num_inp == age:
print("猜对了")
tag = False
break
else:
print("猜错了")
count+=1
if count == 3:
ord = input ("continue? Y/N>>:")
if ord in Y:
tag = True
elif ord in N:
tag = False
7、运用所学知识，打印以下图案：
、、、python
*
***
*****
*******
*********
、、、
print("'
*
***
*****
*******
*********
''')
list = [" *"," ***"," *****"," *******","*********"]
for i in list:
print(i)
