Very excellent start here with if/else cases handing user input validation. One more small change to make. If there is invalid input for any of your first three steps, the variables "cell_count", "cell_count2", and "number" are not defined, as they are outside of the scope of the "if" statements.

When they are called in the final conditional, where cell_count and cell_count2 are expected, the program exits with an error, as nothing exists yet to be compared (see image below).

Therefore, it is just a small juxtaposition change to make. My advice would be to combine all three cases into just one if statement at the beginning using "and" (so all cases must be true to proceed), and if all conditions are satisfied, do the final if statement and calculation inside. In the case that at least one condition is not satisfied, it will prompt your message to the user, and the program will abort gracefully with exit code 1 (no red-text errors).

So close..best of luck.

Thank you for the changes. Simply indent the final if statement to be within the first one, and it will only run if the conditions are satisfied, also add an else statement on that outer if statement to handle any time .isdigit() is false.

Very good start here. Two more things to do. The program must also handle lowercase atcg input. An easy fix for this is just to convert all inputs by using the .upper() method on the first string that is read in.

Secondly, GC content is the (number of Gs plus the number of Cs) divided by the total number of As Ts Cs and Gs, then multiplied by 100. Again, simple arithmetic to add.

I look forward to seeing your next version.
