Game: nine heads and tails

Description of Game: Nine coins are placed in a 3x3 matrix with some face up and some face down. You can represent the state of the coins with the values 0(heads) and 1(tails). (Here are some examples: 000 101 110 101 010 001 100 110 000 100 001 100) Each state can also be represented using a binary number. (For example, the preceding matrices correspond to the numbers: 000010000 101001100 110100001 101110100). There are a total of 512 possibilities. So, you can use the decimal numbers 0, 1, 2, 3, ..., and 511 to represent all states of the matrix. My goal is to write a program that prompts the user to enter a number between 0 and 511 and displays the corresponding 3x3 matrix with the characters H and T. (ex. "Enter a # between 0 and 511: " (7) '''the user entered 7, which corresponds to 000000111. Since 0 stand for H and 1 for T, the output is:''' >>> H H H H H H T T T ) I'm finding this a bit complicated, so I'd appreciate if anyone could help me out with figuring out how to start this out or complete it. Any suggestions or tips are appreciated!

here is a quick code, long time ago I made a code here for transposition encryption. just for fun. your description reminded me of writing that function. so I quickly modified my code to fit your project. it doesn't necessarily have to be that complicated. it's a quick edit of my old code. you can remove a lot. my code can work with greater matrices not only 3x3. check my transposition code and compare it with the modified one here. https://code.sololearn.com/ctuofjkk5Ri4/?ref=app

Convert the decimal number to binary. Then format as three by three matrix.

easier approach. get a number in the specified range convert it to 9 bit digits to get 3x3 grid replace 0 and 1 with H T convert the result to a two dimensional list. with 3 rows and 3 columns. remember my code is not the best solution. it's just a hack of what I already wrote for another purpose.
