"for line in fd" twice

[Thomas Güttler]

Hi!

the following does not work:

"""
fd=open(file)
for line in fd:
    if line.startswith("mymark"):
        break
for line in fd:
    #Read lines after "mymark"
    ....
fd.close()
"""

The second loop misses some lines.

It works with the old way:

"""
while 1:
    line=fd.readline()
    if not line:
        break
"""

instead of "for line in fd"

If you mustnot call "for line in fd" twice, it would 
be nice to get an exception which reminds me about it.
