Question

我正在执行二进制计数器程序。我需要它来打印一个十进制等效项和相应的二进制等效项。...

到目前为止，我已经设法做到了这一点，但是我需要将二进制数从0转换为用户输入值，我一直在研究它，但是我想不通：可以提供任何帮助：）

Please enter number: 12

Decimal: 1  = binary: 1100
Decimal: 2  = binary: 1100
Decimal: 3  = binary: 1100
Decimal: 4  = binary: 1100
Decimal: 5  = binary: 1100
Decimal: 6  = binary: 1100
Decimal: 7  = binary: 1100
Decimal: 8  = binary: 1100
Decimal: 9  = binary: 1100
Decimal: 10  = binary: 1100
Decimal: 11  = binary: 1100
Decimal: 12  = binary: 1100

通过此代码

dec = input('Please enter number')

new_list = []
index = 0
output = ''
counter = 0
dec = int(dec)
upper_range = int(dec)

#for x in range(0,upper_range):



while dec > 0:
        output += str(dec % 2)
        dec = (dec // 2)
output = output[::-1]

new_list.append(output)


while counter < upper_range:
    print('Decimal:', counter + 1, end=' ',)
    print(' = binary:' , *new_list)
    counter = counter + 1

Answer 1

您应该在循环内进行十进制到二进制的转换；否则，它只会转换上限值：

dec = input('Please enter number')

counter = 1
upper_range = int(dec)

while counter <= upper_range:
    binary = ''
    dec = counter
    while dec > 0:
        binary += str(dec % 2)
        dec = (dec // 2)
    binary = binary[::-1]
    print('Decimal:', counter, end=' ',)
    print(' = binary:' , binary)
    counter = counter + 1

Answer 2

我认为这可能会回答您的问题。您可以使用内置的 bin 功能，也可以使用下面的 convTobin 方法手动进行操作。

    #This is with the help of built-in
    n = int(input())
    for i in range(n+1):
        print('Decimal: ',i,' Binary: ',bin(i).split('b')[1]);

   #This is doing it manually
    n = int(input())

    def convTobin(num):
        if num == 0:
            return '0'
        s = ''
        while num:
            s = str(num&1) + s
            num = num>>1
        return s

    for i in range(n+1):
        print('Deciaml: ',i,'Binary: ',convTobin(i))

Answer 3

n = int（input（“请输入数字：”））

对于范围（1，n + 1）中的i：

const mainObject = {
"name": "Central",
"children": [
    {
        "Cellophane `Tape": 10.528979999999999,
        "Cellophane Tape": 79.7194,
        "File Separator": 64.0017,
        "Hard Cover File": 23.2734,
        "Highlighter": 67.2899,
        "Office Chair": 74.2509,
        "Pencil": 74.2509,
        "Tape Dispenser": 67.2899,
        "File Cabinet": 21.058,
        "Plastic Comb Binding": 74.2509,
        "White Board Markers": 74.2509,
        "Binder": 67.2899,
        "Eraser": 64.0017
    }
]
}

let obj = mainObject.children[0]

var arr = [];
for (var key in obj) {
    if (obj.hasOwnProperty(key)) {
        arr.push(key + '=' + obj[key]);
    }
};
let newArray = []
arr.map(item => {
    newArray.push({"name": item.substr(0, item.indexOf('=')),
     "value": item.substr(item.indexOf('=')+1, item.length) })
})
let result = {
  "name" : mainObject.name,
  "children" : newArray
 }
 console.log(result)
