The class is taught by a professor who clearly knows his stuff, and it shows in the lectures. The recorded videos were very informative and related to the homeword. I had a problem with the Autograders that are used for the homework. There is clearly a problem with the manner in which they interpret spacing, and someone should fix this problem. Python is far too dependent on spacing and indentation for it to go unresolved by the teaching staff. I also feel that there is too much of a disconnect in the course between mentors and students. I could not ask any mentor a question and get a straight answer. They merely allude to the problem in the code that is presented to them. I must have spent a day on the last programming assignment. That is partially due to the Autograder's interpretation of spacing, and partially due to unfamiliarity with the language. This is the first time we're writing code, and the problems seem to assume that we are experts. There are not examples of how to manipulate code, followed by homework that varies slightly from what is presented. I am very nervous about continuing in the python specialization. If I can spend a day correcting code due to Autograder problems interpreting spacing and other issues, how long will I require for the code that I'll have to write in future classes? Forget about reaching the professor. He's disconnected, and his phone line doesn't seem to work, or is always busy. There is no one else who can be reached, except the mentors via the Forum, who only provide some perspective on code, but no direct help.
