关于一道练习题，使用range(start, end, step)

循环. 编写一个程序, 让用户输入三个数字: (f)rom, (t)o, 和 (i)ncrement . 以 i

为步长, 从 f 计数到 t , 包括 f 和 t . 例如, 如果输入的是 f == 2, t == 26, i == 4 , 程序

将输出 2, 6, 10, 14, 18, 22, 26.

f1, t1, i1 = raw_input('pls input three num:').split()

f = int(f1)

t = int(t1)

i = int(i1)

a = max(f, t)

b = min(f, t)

c = (a-b)/i

if (a-b)/i ==0:

for n in range(0, c+1):

m = b + n*i

n = n+1

print 'The num list is %d'%(m)

else:

for n in range(0, c+1):

m = b + n*i

n = n+1

print 'The num list is %d'%(m)

print 'The num list is %d'%(a)

很麻烦对不对？？有个更简单的：

f1, t1, i1 = raw_input('pls input three num:').split()

f = int(f1)

t = int(t1)

i = int(i1)

a = max(f, t)

b = min(f, t)

for n in range (b, a, i):

print 'The num lis is %d'%(n)

print 'The num lis is %d'%(a)

巧妙使用range(start, end, step)方法
