1.判断这个数对2取余是否为0,为0则为偶数
sum = 0
a = 0
while a <= 100:
if a % 2 == 0:
sum =sum + a
print(a)
a = a + 1
print('1-100之间的偶数和',sum)
2.判断这个数对2取余是否为0,为0则为偶数,0的bool值为FALSE,FALSE就不执行,所以就是计算的奇数的和
sum = 0
a = 0
while a <= 100:
if bool (a % 2):
sum =sum + a
print(a)
a = a + 1
print('1-100之间的偶数和',sum)
3.判断这个数对2取余是否为0,为0则为偶数,0的bool值为FALSE,FALSE就不执行,所以就是计算的奇数的和,再加个not就是计算的偶数的和
sum = 0
a = 0
while a <= 100:
if not bool (a % 2):
sum =sum + a
print(a)
a = a + 1
print('1-100之间的偶数和',sum)
