This is a very relevant question. I would expect the new keyword would
break lots
of modules. However measuring is better than speculating.
$ echo count_name.py
"""
Count the occurrences of a name in a Python script. For instance:
$ find /usr/lib/python2.4 -name \*.py | xargs python2.4 count_name.py
create
"""
import sys, tokenize, token
def count_name(name, script):
"Count the occurrences of a Python name in a script"
counter = 0
for tok_code, tok_value, (srow, scol), (erow, ecol), line in \
tokenize.generate_tokens(file(script).readline):
if tok_code == token.NAME and tok_value == name:
counter += 1
print 'line %s: %s' %(srow, line),
if counter: print '*** %s ***\n' % script
return counter
if __name__ == '__main__':
name = sys.argv[1]
scripts = sys.argv[2:]
total = sum(count_name(name, script) for script in scripts)
print 'Found %d occurrences of %r' % (total, name)
Here is the output on my box:
