Please don't flag my answer instantaniously, because I searched several other questions that didn't solve my problem, like [this.](https://stackoverflow.com/questions/3392354/append-values-to-a-set-in-python)

I'm trying to generate a python set of strings from a csv file. The printed pandas dataframe of the loaded csv file has the following structure:

```
   0
0  me
1  yes
2  it

```

For a project I need this to be formatted to look like this

```
STOPWORDS = {'me', 'yes', 'it'}

```

I tried to do this by the following code.

```
import pandas as pd

df_stopwords = pd.read_csv("C:/Users/Jakob/stopwords.csv", encoding = 'iso8859-15', header=-1)

STOPWORDS = {}
for index, row in df_stopwords.iterrows():
    STOPWORDS.update(str(row))

print(STOPWORDS)

```

However, I get this error:

```
dictionary update sequence element #0 has length 1; 2 is required

```

When I use the `STOPWORDS.update(str(row))` I get the this error:

```
'dict' object has no attribute 'add'

```

Thank you all in advance!
