Separate digits using Python

Question

I'm looking for an elegant way to separate numbers in a single digits

For example 20 to be 2, 0

The way that I found is using a list comprehension: [int(num) for num in str(number)]

Is there another way to do that?

Answer 1

Try this:

num = 20
digits = []
for x in range(0,len(str(num))):
    digits.append(int(str(num)[x]))

print(digits)

Answer 2

请尝试以下操作：

digits_list = list(str(num))

Answer 3

a math solution (this only works with positive numbers as is):

import math

def get_digits(n):                                                              

    if n == 0:                                                                  
        return [0]                                                              

    digits = []
    while n:
        digits.append(n % 10)
        n = n // 10                                                                                

    return list(reversed(digits))   

for n in [0, 1, 10, 235, 5555]:                                                 
    print(n, get_digits(n))   

output

0 [0]
1 [1]
10 [1, 0]
235 [2, 3, 5]
5555 [5, 5, 5, 5]
