[PATCHES] Do not use letter similar to numbers in python code

[Lukas Slebodnik]

ehlo,

Running pycodestyle-2.6.0 currently reports cases which is one of a set of three 
style checks to avoid ambiguous single letter names which look like numbers

./src/tests/python-test.py:54:35: E741 ambiguous variable name 'l'
./src/tests/python-test.py:102:38: E741 ambiguous variable name 'l'
./src/tests/intg/krb5utils.py:101:27: E741 ambiguous variable name 'l'
./src/tests/intg/krb5utils.py:116:23: E741 ambiguous variable name 'l'
./src/tests/intg/krb5utils.py:140:28: E741 ambiguous variable name 'l'
