pandas移除重复项

import pandas as pd
from pandas import *
import numpy as np
data = DataFrame({‘k1’:[‘one’]*3+[‘two’]*4,’k2’:[1,1,2,3,3,4,4]})
print(data)
print(data.drop_duplicates())

如果希望对指定的列进行重复值删除则

import pandas as pd
from pandas import *
import numpy as np
data = DataFrame({‘k1’:[‘one’]*3+[‘two’]*4,’k2’:[1,1,2,3,3,4,4]})
print(data)
print(data.drop_duplicates(‘k1’))

加一个列名参数就可以了
