Quark’s Outlines: Python Execution Model Overview, Historical Timeline, Problems & Solutions An Overview of the Python Execution Model What is the Python execution model? When you run a Python program, Python follows a process to decide what happens and in what order. This process is called the Python execution model. It controls how code is grouped, how values are stored, and what happens when things go wrong. Python organizes your code into code blocks. Each block runs in an execution frame, which stores the block’s state and connects to the next block. Each frame uses one or more name spaces to hold names and values. When something goes wrong, Python raises an exception. These four ideas — code blocks, execution frames, name spaces, and exceptions — make up the execution model. Python lets you run code using a frame that manages blocks, names, and errors. def greet(): name = "Ada" print("Hello,", name) greet() # prints: # Hello, Ada Here, greet() runs inside a new code block and
