This decorator works by storing the time just before the function starts running in line 10 and just after the function finishes in line 12. The runtime of the function is then the difference between the two, calculated in line 13. You use time.perf_counter(), which does a good job of...

Python 3.8 removesSETUP_LOOP,SETUP_EXCEPT,BREAK_LOOP, andCONTINUE_LOOP, instructions which may make control-flow detection harder, lacking the more sophisticated control-flow analysis that is planned. We'll see. Currently not all Python magic numbers are supported. Specifically in some versions of ...
In this case, our list will have two values: the IP address (which we put into the addrString variable) and the CIDR notation (which we put into the cidrString variable. We tell split to use the slash to determine where to break the string into our list elements. Now we'll want to...
break else: # "Continue" starts the next iteration # of the loop. It's rather useless here, # as it's the last statement of the loop. continue else: # The "else" clause is optional and is # executed only if the loop didn't "break". pass # Do nothing if rangelist[1] == 2...

ContinueF5Run code until you reach the next breakpoint. Step IntoF11Run the next statement and stop. If the next statement is a call to a function, the debugger stops at the first line of the called function. Step OverF10Run the next statement, including making a call to a function (ru...
Like many other programming languages, Python supportsmodularity, in that you can break large chunks of code into smaller, more manageable pieces. You do this by creatingfunctions, which you can think of as named chunks of code. Recall this diagram fromChapter 1, which shows the relationship be...
