Question: I have a table with data for multiple continents. Now I want to delete every row where the continent isn't Europe or Africa.
With:

```
df1 = df1.loc[(df1["region"] == "Europe")]

```

I get every row with "Europe" but I miss the "Africa" ones.
Is there a way to include an "or"-operator? It doesn't work for me.

Answer: 
you can use

```
df1 = df1.loc[(df1["region"].isin(["Europe", "Africa"]))]

```
Also option `df1[df1["region"].isin(["Europe", "Africa"])]`
