“列表”对象不能解释为整数 - 有没有办法将列表转换为整数？

Question

now I am new to the python language, only that in one subject they ask us to do the homework with this language and it is to investigate on our own. In this part of code I first declare the range with the range (0-1024) method, and the random numbers are generated with the sample method, and I believe that these are saved in a list, so what I want to do next is that these Numbers that were generated randomly convert them to binary, but I get this error: "TypeError: 'list' object cannot be interpreted as an integer"

So I don't know if there is a way to convert a list to whole numbers or I don't know what else they would recommend me to do ...

This is my code:

y = list(range(0, 1024))
numRandom = sample(y, 10)
print(numRandom)
print(bin(numRandom))

Answer 1

您可以使用列表理解来创建一个新列表，其中包含原始列表中每个数字的二进制表示。

print([bin(x) for x in numRandom])

Answer 2

As the error says, numRandom is a list, not an integer. Specifically, it's a list of ten random int s.

To apply the bin function to the first element of the list, you could do:

print(bin(numRandom[0]))

You could iterate over the list and do this to each one with a for loop:

for num in numRandom:
    print(bin(num))

Or you could build a list of binary representations with a list comprehension:

print([bin(num) for num in numRandom])

Answer 3

Using Map

print([*map(bin, random.sample(y, 10))])

Or Using List Comprehension

print([bin(x) for x in random.sample(y, 10)])
