"with" statements are also overlooked:

import linecache, sys

def tracefunc(frame, event, arg):
    lineno = frame.f_lineno
    print "Trace", event, lineno, linecache.getline(__file__, lineno).rstrip()
    return tracefunc

def do():
    x = [ 1 ]
    for i in range(2):
        try:
            x[i]
        except IndexError:
            break

    with open(__file__) as f:
        print len(f.read())

sys.settrace(tracefunc)
do()


Produces:

Trace call 8 def do():
Trace line 9     x = [ 1 ]
Trace line 10     for i in range(2):
Trace line 10     for i in range(2):
Trace line 12             x[i]
Trace line 10     for i in range(2):
Trace line 12             x[i]
Trace exception 12             x[i]
Trace line 17         print len(f.read())
397
Trace return 17         print len(f.read())
