When I first learned Python, I worked for a Java shop. Occasionally I'd have to do serious text-processing tasks which were much easier to do with quick Python scripts than Java programs. For example, if I had to parse a complex CSV file and figure out which of its rows corresponded to rows in our Oracle database, this was much easier to do with Python than Java.
More than that, I found that learning Python made me a much better Java programmer; having learned many of the same concepts in another language I feel that I understand those concepts much better. And as for what makes Python easier than Java, you might check out this question: Java -> Python?
