pythoners,
是不是我眼花了,下面的代码有编译错误,5555555
.................................................
outfilew = None
try:
outfilew = open(outfile,'a',1024)
outfilew.write('Find %s lines in file: %s' % (
len(outLines), filename))
outfilew.writelines(outLines)
except IOError:
print 'Find %s lines in file: %s' % ( len(outLines), filename)
print '\n'.join(outLines)
finally :
if outfilew:outfilew.close()
.................................................
> D:\software\Python24\pythonw.exe -u "D:\_tmp_\listjava.py"
File "D:\_tmp_\listjava.py", line 47
finally :
^
SyntaxError: invalid syntax
这是什么错误???
