## 使用while循环输入 1、2、3、4、5、6、8、9、10
方法一:
1 n = 1
2 while n < 11:
3 if n == 7:
4 pass
5 else:
6 print(n)
7 n += 1
方法二:
1 a = 0
2 n = 1
3 while a < 10:
4 if n == 7:
5 pass
6 else:
7 print(n)
8 n += 1
9 a += 1
##输出1-100内的所有数
1 n = 1
2 while n < 101:
3 print(n)
4 n += 1
##输出1-100内的所有奇数
1 n = 1
2 while n < 101:
3 temp = n % 2
4 if temp == 0:
5 pass
6 else:
7 print(n)
8 n += 1
##输出1-100内的所有偶数
1 n = 1
2 while n < 101:
3 temp = n % 2
4 if temp == 0:
5 print(n)
6 else:
7 pass
8 n += 1
##求1-100的所有数的和
1 n = 1
2 sum = 0
3 while n <101:
4 ## print(n)
5 sum = sum + n
6 n += 1
7 print(sum)
##求1-2+3-4+5.。。。99的所有数的和
1 n = 1
2 sum = 0
3 while n < 100:
4 temp = n % 2
5 if temp == 0:
6 sum = sum - n
7 else:
8 sum = sum + n
9 n += 1
10 print(sum)
