我需要打印’x / y’的结果,但它总是返回’0′.当我打印’x’时,它正确地告诉我,当我打印’y’时它正确告诉我但是当我打印’x / y’时它表示0. 这是我的代码： import random y = 0 x = 0 p = 1 while True: i = [random.randint(1,100), random.randint(1,100), random
我有一份清单清单： sample = [['TTTT', 'CCCZ'], ['ATTA', 'CZZC']] count = [[4,3],[4,2]] correctionfactor = [[1.33, 1.5],[1.33,2]] 我计算每个字符(pi)的频率,将其平方然后求和(然后我计算het = 1 – sum). The desired output [[1,2],[1,2]] #NOTE: This

我尝试在Python 3.3中执行以下类型转换操作 int( 10**23 / 10 ) Output: 10000000000000000000000 并且在增加一个或更多的功率之后 int( 10**24 / 10 ) Output: 99999999999999991611392 int( 10**25 / 10 ) Output: 999999999999999983222784 为什么会这样？虽然像一个简单的

如何在MySQL中正确划分两个DECIMAL值并获得精确到列类型中定义的位数的结果？ 例： select cast(1/2 as decimal(4,4)), cast(1 as decimal(4,4))/2, cast(1 as decimal(4,4))/cast(2 as decimal(4,4)); 结果： '0.5000', '0.49995000', '1.00000000' 为什么第二个结果是否真空？为什么

使用python的V3,我创建： class NewInt(int): def __rtruediv__(self, num): print('in here') x = NewInt(5) 343 / x # called rtruediv as I expect, but 343.3 / x # does not call rtruediv 不知道为什么这是因为： x / 343 x / 343.3 #both will call truediv
我在MySQL中看到一些与用户创建的函数相关的奇怪行为.我会尽可能简化这一点. mysql> SELECT 1 / 50 +--------+ | 1/50 | +--------+ | 0.0200 | +--------+ 1 row in set (0.00 sec) 到现在为止还挺好.现在我创建一个函数来进行这个除法并调用函数： mysql> delimiter $$ mysq
