    print(code_n)        # <<<<< This is problem



result = 0

Answer 1

To answer your question, You can use globals() which returns a dictionary of the variables defined in the environment, and you can call get() on this dictionary object to get the value of a variable by its corresponding name.

code_0 = 0
code_1 = 1
code_2 = 2

for n in range(3):
    print(globals().get(f"code_{n}"))

#output:
0
1
2

But instead of accessing globals() directly, you can define codes list with the list of values and get the values in the list by index:

codes = [1,2,3]
for i in range(len(codes)):
    print(codes[i])

#output:
1
2
3

Answer 2

assign result as a list and append these code into it, then print will show all codes.

result = []

for n in range(3):
  
  result.append(code_n)

print
