How to move the cursor above the first line without overighting it

Here is my code

print("1")print("2")

My desired output

21

I tried using ansi characters but the second line is overighting the first line

print("1")print("\033[3A2")  

output

2

How can I achieve my desired output using other means apart from loop to reverse the order of the print statement

I prefer ansi characters, terminal(), but I will also use other methods
