How can I print binary combinations?

Question

The user input should specify the number of bits.
Example:
#if user enters 1, then
output:
0
1

#if user enters 2, then
output:
00
01
10
11

#if user enters 3, then
output:
000
001
010
011
100
101
110
111

Further, every output instance should be included in list, dictionary or whatever and can be accessible. Also, If I access an instance, can I separate out each digit?
110 -->1, 1, 0

Answer 1

There's a built in function to transferm binary to int and int to binary
and the int() function can do that also ,it takes two parameters the number and the base u want that number to be in and transfer it to intger in that base

and to separate the numbers just make a for loop
example
numbers=[`11`,`22`,`33`,`45`,`55`,]
#store them as a string and
#make an empty list
diget=[]
for n in numbers:
n [0].append (diget)
n [1].append(diget)

and if u want to make it more efficient u can add an if statement to check how many digets in the string
