Hello Vishwanatha, the filters in GNU Radio are all written in C++, and the mathematical core functionality is implemented in several versions for different machines in C with a mixture of SIMD intrinsics (read: close-to-assembler instructions), because filtering is often a very computationally expensive part in signal processing and therefore must be optimized heavily to make systems work in real time.
However, you can use/construct these filters from python. If you want to see how that would look like, start the gnuradio-companion, connect a "Null Source", a "Low Pass Filter", and a "Null Sink". Parameterize the filter block. Save the file, and click on the "generate" button. You'll see a message in the box at the bottom like 'Generating: "/home/vishwanatha/top_block.py"'. Open that file in a text editor, and look for the lines that contain low_pass.
