#求100内奇数和while\for..in循环

sum = 0

i = 1

while i <= 100:

    sum += i

    i += 2

print(sum)

sum = 0

for i in range(1,101,2):

    sum += i

print(sum)

#求100内偶数while\for..in循环

sum = 0

i = 0

while i <=100:

    sum += i

    i += 2

print(sum)

sum = 0

#range函数end时不包括当前数值，所有注意101.

for i in range(0,101,2):

    sum += i

print(sum)
