filter all the columns values code example

Example 1: only keep rows of a dataframe based on a column value

df.loc[df['column_name'] == some_value]

Example 2: html table filter by all columns

function myFunction() {
  var input, filter, table, tr, td, i;
  input = document.getElementById("myInput");
  filter = input.value.toUpperCase();
  table = document.getElementById("myTable");
  var rows = table.getElementsByTagName("tr");
  for (i = 0; i < rows.length; i++) {
    var cells = rows[i].getElementsByTagName("td");
    var j;
    var rowContainsFilter = false;
    for (j = 0; j < cells.length; j++) {
      if (cells[j]) {
        if (cells[j].innerHTML.toUpperCase().indexOf(filter) > -1) {
          rowContainsFilter = true;
          continue;
        }
      }
    }

    if (! rowContainsFilter) {
      rows[i].style.display = "none";
    } else {
      rows[i].style.display = "";
    }
  }
}

Example 3: filter df by column value

# does year equals to 2002?
# is_2002 is a boolean variable with True or False in it
>is_2002 =  gapminder['year']==2002
>print(is_2002.head())
0    False
1    False
2    False
3    False
4    False
