## then i did this to use it on the dataframe:
df_news["normalized_article"] = df_news["article"].apply(normalize)

## and finally to make the .txt i did this:
with open("dataset/article1.txt", "w", encoding="utf-8") as outfile:
    for i in df_news["normalized_article"][1:2]:
        outfile.write(i)
