int to array python

# Declare a number
a = 12345
#Number to list
a_list = [int(x) for x in str(a)]

res = [int(x) for x in str(num)] 

# Python3 code to demonstrate  
# conversion of number to list of integers 
# using map() 
  
# initializing number  
num = 2019
  
# printing number  
print ("The original number is " + str(num)) 
  
# using map() 
# to convert number to list of integers 
res = list(map(int, str(num))) 
  
# printing result  
print ("The list from number is " + str(res))
