使用pandas，特别是pandas.DataFrame.drop_duplicates

import pandas as pd

df = pd.read_excel('my_xls.xls')

# Find and drop duplicates in Column1
df['Column1'] = df.Column1.drop_duplicates()

# Open pandas ExcelWriter and write to *.xls file
with pd.ExcelWriter('my_xls.xls') as writer:
    df.to_excel(writer, index=False)
