Check a dataframe column

check_cols.rs

pub fn deal_with_columns<P: AsRef<Path>>(path: P) -> () {
    /* Examples to deal with column and column names and enumerate */
    let df = read_csv(&path).unwrap();
    // column functions
    let columns = df.get_columns(); // you can do for column in columns{}
    let columname = df.get_column_names(); 

    // example like Python for i, val in enumerate(list, 0):
    for (i, column) in columns.iter().enumerate(){
        println!("{}, {}", column, columname[i]);
    }
