Error in code "Time to slice and dice" from course "NLP Course"
You should open an issue in the NLP course website / github page. I'm closing this issue if you don't mind ok, i don't mind, i'll mark the error there
### Describe the bug

When we execute code 
```
frequencies = (
    train_df["condition"]
    .value_counts()
    .to_frame()
    .reset_index()
    .rename(columns={"index": "condition", "condition": "frequency"})
)
frequencies.head()
```
answer should be like this

condition      | frequency
birth control | 27655
depression    | 8023
acne              | 5209
anxiety          | 4991
pain               | 4744

but he is different

frequency      | count
birth control  | 27655
depression    | 8023
acne              | 5209
anxiety          | 4991
pain               | 4744

this is not correct, correct code
```
frequencies = (
    train_df["condition"]
    .value_counts()
    .to_frame()
    .reset_index()
    .rename(columns={"index": "condition", "count": "frequency"})
)
````

### Steps to reproduce the bug

```
frequencies = (
train_df["condition"]
.value_counts()
.to_frame()
.reset_index()
.rename(columns={"index": "condition", "condition": "frequency"})
)
frequencies.head()
```

### Expected behavior


condition      | frequency
birth control | 27655
depression    | 8023
acne              | 5209
anxiety          | 4991
pain               | 4744
