# open file to line number
self.view.window().open_file("{0}:{1}:{2}".format(file_path_full, line_num, 0), sublime.ENCODED_POSITION)
#                                                                           ^
#                                                                   You can replace this 0 with a column variable (I think - not tested)
# 
# At this point, file_path_full is:
# C:\Users\Austin\Desktop\test.txt
# 
# Of course Python prints two backslashes for escape character reasons, but that will not have an adverse effect on the code itself.
# 
# line_num is:
# 82
# 
# really any integer will do.
