A programmable logic controller (PLC) is an expensive device generally used when you make good money from what you make
If your induction heater was used as part of a large production line, then it is likely that a PLC is used to control that line, turning motors, cylinders and other machines on and off. They're not designed to replace electronics, they're designed to replace relay logics. It would be to slow, big and impractical for your task, and i have yet to come across a PLC with PWM outputs. If a PLC is used to drive a DC motor then the most common way to achieve this would be to use either an analog 4-20mA signal or a bus signal like Profibus to drive a separate PWM controller. A PLC is basically a computer with galvanically protected input and output cards, using either bitwise on/off, analog signals or signal buses.
They are expensive, but they are also very quick and easy to program or monitor, and they are very reliable.
Umm, back to topic. Can an AVR or a PIC be programmed in Python?

Not really, Python is an interpreted language that is not written for efficiency so it would be awfully slow. In addition it would have problems with available memory even if you managed to fit the interpreter on one of those small chips.
