while循环中仅将最后一项追加到列表中（Python）

Question

I'm trying to create a program that gets each digit of an inputted number into a list using a while loop. However, it only appends the last digit of the number to the list.

Code -

num = int(input("Enter a number: "))
numstr = str(num)
numlen = len(numstr)
x = 0

while x < numlen:
    digits = []
    a = numstr[x]
    digits.append(a)
    x = x + 1

print(digits)

So if I were to put in 372 as the number, the list would just simply be ['2'] with a length of 1 .

Answer 1

试试这个代码：

digits = [i for i in str(num)]

Answer 2

You cannot do better than digits = list(str(num)) . In fact, since input returns a string, even the conversion to a number is not necessary:

num = input("Enter a number: ")
digits = list(num)

(You still may want to ensure that what's typed is indeed a number, not a random string.)
