I have data stored in the list. Below you can see my data.

```
listName = ['column1','column2','column3','column4']

```

Now I want to drop elements with titles `'column2'` and `'column3'`

I tried this command but is not work.

```
listName=listName.drop(['column2','column3'],axis=1)

```

Can anybody help me how to solve this problem?
