In the previous sections, you have seen a lot of examples already of how you can call a function. Calling a function means that you execute the function that you have defined - either directly from the Python prompt or through another function (as you will see in the section “Nested Fun...
As a developer, you care more that your library successfully called the system function for ejecting a CD (with the correct arguments, etc.) as opposed to actually experiencing your CD tray open every time a test is run. (Or worse, multiple times, as multiple tests reference the eject code...
It's created at function call, not at function definition, so you'll have as many different local scopes as function calls. This is true even if you call the same function multiple times, or recursively. Each call will result in a new local scope being created. Enclosing (or nonlocal) ...
It generates a PNG file showing an modules's function calls and their link to other function calls, the amount of times a function was called and the time spent in that function. Typical usage: pycallgraph scriptname. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. ...
each recursive call to a function creates its own scope /environment flow of control passes back to previous scope once function call return value factorial同样可以用iteration实现: def factorial_iter(n): prod = 1 for i in range (1, n+1): prod *= i return prod ...

You can now profile simply using a with block, or a function/method decorator. This will profile the code and print a short readout into the terminal. (#327) Adds new, lower overhead timing options. Pyinstrument calls timers on every Python function call, which is fine on systems with ...

time. However, the total time within this function is 0. This means that we need to optimize functions that are called byreadline(). We suspect it might be the read operation of SSL Socket. The entry "4/3" indicates thatsessions.py:send()is called 3 times plus 1 recursive call. ...
