打印一空行

改成这样,就可以了 应该 from math import sqrtdef sim_distance(prefs,personal1,personal2): si={} for item in prefs[personal1]: if item in prefs[personal2]: si[item]=1 if len(si)==0: return 0 //这一句有问题!! sum_of_squares=sum...

"TyprError: range() integer end argument expected, got float." Because math.sqrt(num) returns a float number, but what function range() needs is a int, so you may use for i in range(2, int(math.sqrt(number))): instead.

def test(*args):j = len(args)-1for i in args:if i == args[j-1]:print(i,end =', and ')elif i == args[j]:print(i)else:print(i,end =', ')spam = ['apples', 'bananas', 'tofu', 'cats']test(*spam)

把输入的数据转换类型就可以了,输入的是字符串,转化为数据类型就好 a = input('goal(M RMB)')p = input('prijs van kippen(RMB)')c = input('cycle(dagen)')a = float(a)p = float(p)c = float(c)d = a*10e6/pw = d*7t = c*dprint('verkoopbed...

args没有func这个方法, 你需要查看下ps.parse_args()返回值是什么,然后看这个返回值有没有func这个方法

def get_year_count(): result = dict() for k, v in Beatles_Discography.items(): if result.get(v, None) is None: result[v] = 1 else: result[v] += 1 result = sorted(result.iteritems(), lambda x:x[1], reverse=True) return result de...

分为三步 产生随机数 筛选3位数,小于1000 排序输出 import randomx=[random.randint(1,10000) for i in xrange(1000)]y=[i for i in x if i

按照题目要求编写的判断循环数的Python程序如下 num=input("请输入一个正整数:")flag=Truefor i in range(1,len(num)+1): flag1=False number=str(int(num)*i) if len(number)
