cara menemukan nilai terdekat dalam kolom python
result_index = df['col_to_search'].sub(search_value).abs().idxmin()
#.sub(search_value) subtracts search_value from the df[col_to_search] to make the nearest value almost-zero,
#.abs() makes the almost-zero the minimum of the column,
#.idxmin() yields the df.index of the minimum value, or the closest match to search_value.
