Extracting Consecutive Rows from DataFrame Based on Lane ID Differences

The given code snippet iterates through the enumerated list of the differences between elements in "lst_laneId". If the difference is not zero, the index of that element is appended to "lst_index".\n\nThen, for each index in "lst_index", two copies of rows from the DataFrame "data_c" are created. The first copy "data_c_c" contains the row at the current index, and the second copy "data_c_c_1" contains the row at the next index.\n\nIt seems like the code is trying to extract consecutive rows from "data_c" where the corresponding elements in "lst_laneId" are not equal.
