这样也行的。，
sum = 0
x = 1
while sum < 100:
sum = 2*sum + x
print sum
sum = 0
x = 1
while sum < 100:
sum = 2*sum + x
print sum

你没有打印语句啊，你对变量L的赋值语句没有错。半角全角问题？或者是你错在没写上来的其他地方？在逗号后面留一个空格字符是为了书写美观易读，不是强制要求的。同理，在=，#前后加空格也是这个目的。

print 'Hello,',arg,'.'

import math
def quadratic_equation(a, b, c):
x=math.sqrt(b*b-4*a*c)
return ((-b+x)/2*a),((-b-x)/2*a)
print quadratic_equation(2, 3, 0)
print quadratic_equation(1, -6, 5)
这个哪儿错了啊

答案水，我认为是“Python”和“Guido”都是小写 ^_^
s = 'python was started in 1989 by "guido".\npython is free and easy to learn.'
print s
s = 'python was started in 1989 by "guido".\npython is free and easy to learn.'
print s
