刚刚那个码错了for x in [1,2,3,4,5,6,7,8,9]: for y in [1,2,3,4,5,6,7,8,9]: if x<y: print x*10+y有引号的是字符串，字符串和数字是不同数据类型，不能进行四则运算

sum = 0
x = 0
while True:
x = x + 1
if x > 100:
break
elif x%2==0:
continue
else:
sum=sum+x
print sum
x = 0
while True:
x = x + 1
if x > 100:
break
elif x%2==0:
continue
else:
sum=sum+x
print sum

这属于数学计算题了，花了好久才整出来
x1 = 1
d = 3
n = 100
x100 = (n-1)*d+1
s = (x100+x1)*(n/2)
print s
x1 = 1
d = 3
n = 100
x100 = (n-1)*d+1
s = (x100+x1)*(n/2)
print s

s = 'Python was started in 1989 by \" Guido \". \n Python is free and easy to learn. '
print s

x1 = 1
d = 3
n = 100
x100 = (n-1)*d+1
s = ((n-1)*n*d)/2+n*x1
print s,x100
d = 3
n = 100
x100 = (n-1)*d+1
s = ((n-1)*n*d)/2+n*x1
print s,x100
