Speaking to Computers

Computers only understand machine code - pure binary (1s and 0s). But humans can't easily read or write binary! High-level languages like Python are like speaking English - easy for us but need translating. Low-level languages like Assembly are closer to machine code - harder for us but faster for computers. It's a trade-off: programmer convenience vs computer efficiency.
