How print every line of a python script as its being executed (including the console)?

Question

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(object): def __init__(self, func): self.func = func def __enter__(self): sys.settrace(self.func) return self def __exit__(self, ext_type, exc_value, traceback): sys.settrace(None) def monitor(frame, event, arg): if event == "line": file_dict = dict(enumerate("{}".split("|"))) line_number = frame.f_lineno-25 if line_number > 0: print "line " + str(line_number)+ ": " + file_dict[line_number] return monitor def run(): {} with SetTrace(monitor): run() """ python_string_example = """ im…

Accepted Answer

You can use the trace module for this

If your 4 lines of code are in tmp.py, calling it as

```
python -m trace -t tmp.py 
```

Produces the following output

```
 --- modulename: tmp, funcname: <module>
tmp.py(1): import time
tmp.py(2): print 'hello'
hello
tmp.py(3): time.sleep(3)
tmp.py(4): print 'goodbye'
goodbye
 --- modulename: trace, funcname: _unsettrace
trace.py(80):         sys.settrace(None)
```
