This is my dataframe. I want to create a new column named `mpg_high`

[![enter image description here](https://i.stack.imgur.com/RrIEe.png)](https://i.stack.imgur.com/RrIEe.png)

The condition of the column is:
`mpg_high = 1` if `mpg > average mpg` (this is the mean of mpg where I placed `np.mean(df.mpg) else = 0`.

I tried various methods but kept getting syntax errors. How can I do this?

Thanks in advance
