I am a godot user and a Python user. In pygame, in a simple game like pong, I had an average of 55-60 FPS in fullscreen. In addition, when ported to Kivy, I had an average FPS of 60-70FPS. But when I coded this in Godot, and got an average FPS of 180-200 in the viewport, while profiling! My program was extremely similar in both, and I wasn't static typing at all in Godot. Why is pygame so slow and is there anyway I can make it faster?

Godot is using OpenGL ES for drawing to the window. PyGame is based on SDL, which does not use hardware graphics primitives at all. You could also port your game to Kivy, which supports OpenGL ES too.
In terms of pushing pixels to the screen, graphics being drawn with a CPU Vs running on GPU is not a contest the CPU can ever win. That said, for a whole lot of game styles, PyGame is fast enough. There is absolutely no point updating the screen faster than the monitor is refreshing.
I would expect a basic Pong in PyGame to always run at full-FPS. On a huge high-DPI display, maybe even erasing the background is enough of a pixel-load to drop the FPS.
