Answer 1

One idea you could use would be to pandas rank method, group by the needed columns

df["RANK"] = df.groupby("Column_1")["Column_2"].rank(method="first", ascending=True)

This should return dataframe by grouping, so three rows of dupes should be ranked 1,2 and 3 respectively. From there, you can take the subset of the dataframe where rank=1 and this will give you a dataframe with no dupes.

Answer 2

Create a new match column then drop_duplicates

# sample df
df = pd.DataFrame({'a': [1,1,1,1,1],
                   'b': ['Bulldogs at Aztecs', 'Aztecs at Bulldogs', 'Bearcats at Huskies', 'Huskies at Bearcats', 'something else']})

# list comprehension and sort words in string 
df['match'] = [' '.join(sorted(x.split())) for x in df['b'].values]

#    a                    b                match
# 0  1   Bulldogs at Aztecs   Aztecs Bulldogs at
# 1  1   Aztecs at Bulldogs   Aztecs Bulldogs at
# 2  1  Bearcats at Huskies  Bearcats Huskies at
# 3  1  Huskies at Bearcats  Bearcats Huskies at
# 4  1       something else       else something

# drop_duplicates
df.drop_duplicates(['a', 'match'], keep='first').drop(columns='match')

#    a                    b
# 0  1   Bulldogs at Aztecs
# 2  1  Bearcats at Huskies
# 4  1       something else
