Hi, apparently (as seen in my school's online library page) my school has Problems and Theorems in Analysis by Polya and Szego. I hear this book is really good, but I am wondering if this book is good for learning real analysis. I haven't looked inside the book, but is it like an inquiry based learning approach? Is it a self-contained book with definitions, that can in theory (as in, of course maybe having outsource a bit if the problems are too difficult) learn analysis from? I am in general trying to find guided discovery/inquiry based problem books for most subjects since I think they are amazing, but whenever I find one, it is usually not very deep. For example, this book seems okay, but doesn't cover much. I was hoping to find one for analysis that is very expansive., and I am hoping Polya and Szego's book is of this type. Thanks in advance for any response.
