Between-Markers-Simplified.py

# You are given a string and two markers (the initial one and final). You have to find a substring enclosed between these two markers. But there are a few important conditions.

# The initial and final markers are always different.
# The initial and final markers are always 1 char size.
# The initial and final markers always exist in a string and go one after another.
