total = 0 for i in range(1000): if (i%3==0) or (i%5==0): total += i print(total) 注释: range(5)=[0,1,2,3,4] %的意思是求除法的余数 python文艺青年说, 我一行代码搞定 sum(x for x in range(1000) if x % 3== 0 or x % 5== 0) 这里解释一下python列表推导式(list ...
1.python 暴力破解 一行省事。 print(max([x*y for x in range(100,1000) for y in range(100,1000) if str(x*y) == str(x*y)[::-1]])) 评:你省事了,机器就要多跑几十万圈 为了算更大的数(比如12位回文数),就需要优化程序。 解:if str(x*y) == str(x*y)[::-1] 这一句是判断乘...
ProjectEuler上的程序语言排行,Matlab比Python低那么多是因为:1.问题类型原因;2.编程体验原因;3.社区支持原因;4.许可证限制。问题类型原因是指,MATLAB侧重于矩阵运算和科学计算,无法解决其他类型的问题,而Python有丰富的第三方库,可以更轻松地适应各种类型的问题。 1.问题类型原因 ProjectEuler上的问题类型非常多样化,...
