As indicated in other questions: using a position type would make sense, e.g. The results string should not contain any parentheses. In other words: if we reach the if at all, we know that all the ifs before it were false, because otherwise we would already have returned from the method. It is guaranteed that parentheses form a regular bracket sequence. Return true if it is possible to remove one element from the array in order to get a strictly increasing sequence, otherwise return false. 72 stands for H in the ASCII-table, so the first letter is H. You can't just call it and check its result value in a test, for example, you actually have to capture the output from the terminal. This way, the main entry point will only be automatically executed if the module is run as a script, but not if it is imported: Since you intend to run this as a script, it should have a shebang line, something like this: Note: In order to make this answer useful for future readers, I have mostly assumed Python 3.10, which is about to be released soon.

Additionally, you don't need to generate this list yourself, you can use random.sample: You're using this method in several places inside loops. A book called "Code Complete" can be useful in learning different patterns of common mistakes made by programmers, I recommend grabbing a copy. Other letters can be obtained in the same manner. I like the way the status is explicitly kept using the enum; it makes everything that more easy to follow. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior.
