Paul E. Long’s 1971 textbook, "An Introduction to General Topology," provides an accessible, classical approach to point-set topology suitable for undergraduates. The text covers essential topics including axiomatic foundations, topological spaces, and continuous functions, featuring ample exercises for skill development.

The (e.g., compactness, Hausdorff spaces) you are trying to learn
While the book focuses on general topology, Long dedicates significant space to metric spaces. Here, the topology is generated by a specific distance function (metric). This acts as a beautiful full-circle moment for students, showing how the abstract definitions of openness and continuity map directly back to the familiar metrics used in calculus.
