Lstrip not working as expected when the string has "=e" in it.

Python 2.7.11 (default, Jan 22 2016, 08:28:37)

>>> test = "Cookie:  test-Debug=edttrace=expires=1517828996"
>>> test.lstrip('Cookie:  test-Debug=')

It works as documented. Removes characters specified by the argument from the string. In your example the argument contains "e", but doesn't contain "d". Therefore starting characters up to "d" have been removed.

If you see output dttrace.... e is missing 

see working example
>>> test = "Cookie:  test-Debug=edttrace=expires=1517828996"
>>> test.lstrip('Cookie:  test-Debug=')
# e missing here

>>> test = "Cookie:  test-Debug=adttrace=expires=1517828996"
>>> test.lstrip('Cookie:  test-Debug=')
# Works correct here

Please read the documentation again. lstrip doesn't work like you assume:

>>> "cbaabcdef".lstrip("abc")
