I want to learn real analysis nicely. I like Walter rudin real analysis but I have time constraints too. I have red analysis earlier also but I want to fix myself to almost two books for now.. Since in the time period of two to three months maximum it's not possible to read Walter rudin properly. So I thought let me take two books one Walter rudin for motivation and it's elegance and other which would be little easy so that I can cover a good amount of Syallabus as well. So please suggest me a book which I can use with Walter rudin which will give me more details and will be less time taking to go through. I want to know that whether I should go for a calculus book like by Micheal spivak or Adrian banner or any other or understanding analysis by Stephan Abbot ? I know pre calculus. I want to learn those calculus concepts now with more rigour so that It will help me understand rudin more better way.
