inspect

问题 I'd like to print every line of python script as it's being executed, as well as the log from the console as every line is being executed. For example, for this script: import time print 'hello' time.sleep(3) print 'goodbye' I'd like it to generate the following in the console: line 1: import time line 2: print 'hello' hello line 3: time.sleep(3) line 4: print 'goodbye' goodbye See below for my attempt import subprocess as subp python_string = """ import sys import inspect class SetTrace

问题 What is the best way to find all function calls that a function makes? I want to do this at runtime (likely with a decorator). Is the best way to retrieve the source code with inspect (this means that I will have to have access to the source code...so no interactive interpreter support) and then parse it with ast ? Is there a better way? Python 2.7 preferred, but not required. I'd like it to be simple enough to do myself. If others have done it, I would look at the source code so I could

问题 I have been developing a website for a project targeting mobile phones and tablets, currently focusing on using the chrome browser. Much of this development has been done on one phone using a laptop. I had been using the "chrome://inspect/#devices" quite painlessly until I came to test on a different phone, when clicking "inspect" resulted in a white page. The problem seemed to be that as I happened to have no network connection at the time, chrome couldn't access some repository and so didnt

问题 Let's say, I have a bunch of functions a , b , c , d and e and I want to find out if they directly use a loop: def a(): for i in range(3): print(i**2) def b(): i = 0 while i < 3: print(i**2) i += 1 def c(): print("\n".join([str(i**2) for i in range(3)])) def d(): print("\n".join(["0", "1", "4"])) def e(): "for" I want to write a function uses_loop so I can expect these assertions to pass: assert uses_loop(a) == True assert uses_loop(b) == True assert uses_loop(c) == False assert uses_loop(d)
