debian - Working from the prompt, but not from the cron job

I created a script which takes the IP configuration as
input

ifconfig | /usr/bin/python
"/home/michel/Python/sendIp.py"

When
i type that in in the command prompt, the script gets executed well, and the result of
the ifconfig script is available in my
script.

However, when I insert it in my cron
(with crontab -e) like this, it does not read the ifconfig
input

* * * * * ifconfig |
/usr/bin/python
"/home/michel/Python/sendIp.py"

The
input is read in the script like this:
data =
sys.stdin.read()

Try using
the full path to ifconfig in your cronjob.

            ifconfig
/sbin/ifconfig
