12-While循环和For循环至100滴加法

#While循环
num = 0
i = 1

while i <= 100:
    num += i
    i += 1
print(num)
***************************************
#For循环
sum = 0
for i in range(1,101):
    sum +=i
print(sum)
****************************************
#for循环偶数加法
sum100 = 0
for i in range(1,101):
    if  i % 2 == 1:
        continue
    sum100 += i

print(sum100)
