I\'ve heard these terms thrown around describing languages before, like C is not quite a low level language, C++ is a mid level, and Python is a High level
Low level means closer to the machine, and therefore more difficult and more powerful. The higher level you get, the more removed from the machine and "English-like" you get, but you lose a lot of the power and functionality that comes with being able to control the minute details of the machine. Higher level languages also generally tend to protect you more and have much more precautions and checks in place, while lower level languages trust you, so to speak, and let you play around at your own risk.
