自己的作业：
1.
count = 0
while count <= 9 :
count += 1
if count == 7 :
continue
print (count)
2.
count = 1
sum = 0
while count <=100 :
sum = sum + count
count += 1
print (sum)
3.
count = 1
while count <=100 :
print (count)
count += 2
4.
count = 0
while count <= 100 :
print (count)
count += 2
5.
count1 = 1
count2 = -2
sum = 0
while count1 <=99 :
sum = sum + count1 + count2
count1 += 2
count2 -= 2
print (sum)
6.
count = 1
while count <= 3:
code = input('请输入密码：')
if code == '' :
print ('输入正确！')
break
else :
print ('输入错误')
count += 1
if count > 3:
print ('傻叉，错三次了！')
其中第六道题真的难倒我了，试了很多次才做出来，好高兴。希望自己能够喜欢上写代码的这种感觉。
