Python 1-100的输出，偶数的输出，奇数的输出，所有奇数/偶数的和

输出1-10

输出1-10

a = 0
while a <=10:
    print(a)
    a= a+1

输出1到10 的说有偶数/奇数`

for a in range(0,10,2):
    print(a)

结果0 2 4 6 98

a = 1
while a<=10:
  if a%2==1:
    print(a)
  a= a+2

结果 1 3 5 7 9

1到 100 所有偶数和

sum =0
i = 0
while (i<=100):
    if i%2==0:
        sum = sum + i
    i = i + 2
print(sum)
