Removing and Replacing

As mentioned previously, there are two ways to perform removing or replacing operations. Since we used the .str accessor two chapters ago, let's use a lambda function this time.

Opgave

Swipe to start coding

  1. Define a lambda function with a single argument x that will:

    • Remove the '$' characters starting from the left (using the .lstrip() method);

    • Replace all blank spaces (' ') with empty strings ('') (using the .replace() method);

    • Assign the function to the rmv_rpl variable.

  2. Apply the rmv_rpl function to the 'Weekly_Sales' column using the .apply() method and convert it to the float data type.
