My data frame looks like that: 

```
column 1 | column 2
apple    | 3
banana   | 4
carrot   | 1

```

Using

```
print df["column 1"] * df["column 2"] 

returns
appleappleapple
bananabananabananabanana
carrot

```

however I want the words to be spaced out i.e.

```
apple apple apple
banana banana banana banana
carrot

```

Probably really basic but how can this be done? Thank you!!
