You are probably going about solving the problem from the wrong direction:
Try something like this, overly verbose variable names used on purpose:
regHours = context.getMainPrint();
#let a dictionary do the grouping for us
hours_to_libraries_dic = {}
for lib in regHours:
key = lib.Monday + lib.Tuesday + lib.Wednesday + lib.Thursday +
lib.Friday + lib.Saturday + lib.Sunday
try:
# if the key already exists add to the list of libraries
hours_to_libraries_dic[key].append(lib)
except KeyError:
# if the key does not exists, create a new library list
hours_to_libraries_dic[key] = [lib]
#print out the timetable
for lib_group in hours_to_libraries_dic.values():
print " and ".join([lib.libraryName for lib in lib_group])
a_lib = lib_group[0]
print " Monday", a_lib.Monday
print " Tuesday", a_lib.Tuesday
print " Wednesday", a_lib.Wednesday
....(you get the idea)
print " Sunday", a_lib.Sunday
