How to starndarized space in pandas

Here’s my dataset

Id          Two Words
1             jawa timur
2           jawa  barat
3           kalimantan selatan

What I want is only one space between two words, no space otherwise

Id          Two Words
1           jawa timur
2           jawa barat
3           kalimantan selatan

>Solution :

df["Two Words"] = df["Two Words"].str..strip().replace(' +', ' ',regex=True)
