Solution # 2: Now we will see a better and more efficient approach using the Pandas function DataFrame.apply () .
| |
Output:
Let's use DataFrame.apply () Pandas DataFrame.apply () to format Product names in the desired format. Inside the Pandas DataFrame.apply () function, we'll use a lambda function.
