Instructions In this kata, you must create a digital root function. A digital root is the recursive sum of all the digits in a number. Given n, take t
digits = [1,2,3,4,5,6,7,8,9,0] print(min(digits)) print(max(digits)) print(sum(digits)) 0 9 45 4.2.4 列表解析 列表解析(comprehension)将for循环和创建新元素的代码合并为一行,并自动附加新元素。 例如,现在要创建一个包含1~10的平方的列表。 squares = [] for value in range(1,11):...
# Get data types of columns sales.dtypes 销售数据前两列 Revenue被视为对象型数据类型 现在,如果我们想要查看总收入并应用sum方法,结果将是一个连接字符串,而不是所有行中所有收入值的数值总和: sales['Revenue'].sum() 作为一种解决方案,我们首先删除$符号,然后在执行求和操作之前将数据类型更改为' int ':...
(2) or should we sum digits at even (index) position of 1351204, which is 1, 5, 2, 4 which gives a sum of 12 ? (3) or are you talking of a range of numbers from e.g. 1 to 60, where all even numbers have to be summarized ? Thanks for your support. 21st May 2020, 12:...
temp//= 10ifnum==sum:print(num) 运行结果: 注: 在变量lower中设置了下限100,在变量upper中设置了上限2000。 使用了for循环来从变量lower到upper进行迭代。在迭代中,lower的值增加1,并检查它是否为阿姆斯特朗数。 可以更改范围并通过更改变量lower和upper进行测试。该变量lower应小于upper此程序才能正常运行。
