利用for循环和while循环求n – python – 前端，python exe 打包

xStart=raw_input(“please enter the int number:”)

xInt= int(xStart)

count=0

while not xInt==count:

count +=1

print count #你输入多少就从1显示到这个数

还有就是求和：

xStart=raw_input(“please enter the int number:”)

xInt= int(xStart)

count= 0

sum= 0

while not xInt == count:

count += 1

sum += count

print sum

#这里显示的sum是如果你要输入数值5，则显示sum=1+2+3+4+5的值．
