Day9练习

#1、使用while循环输入1 2 3 4 5 6 8 9 10
count = 0
while count < 10:
    count += 1
    if count == 7:
        continue
    print(count)

#2、求1-100的所有数的和
i = 0
m = 0
while i <= 100:
    m = m + i
    i  = i + 1
    
print('1-100的所有数的和:%d' %m)

num = []
for j in range(101):
    num.append(j)
print('1-100的所有数的和%d' %sum(num))

#3、输出1-100内的所有奇数
print('100以内的奇数是：')
i = 1
while i <= 100:
    print(i)
    i = i+2

#4、输入1-100内所有的偶数
print('100以内的偶数是：')
for i in range(1,101):
    if i % 2 == 0:
        print(i)

#5、求1-2+3-4+5...99的所有数的和
odd = []
even = []
for i in range(1,101):
    if i % 2 != 0:
        odd.append(i)
    else:
        even.append(i)
num = sum(odd) - sum(even)
print('1-2+3-4+5...99的所有数的和:%d' %num)
