我有两个具有相同列的熊猫表,如果circuit列中的数据为None,id想要做的就是合并这些列
>> site_routing_data[0]
circuit errors route site mask next_hop error
0 MPLS None 10.10.1.0 Manchester 255.255.255.0 172.5.1.5 NaN
1 MPLS None 10.10.2.0 London 255.255.255.0 172.5.1.5 NaN
2 None None 10.10.3.0 Birmingham 255.255.255.0 172.5.1.5 NaN
3 MPLS None 10.10.4.0 Sheffield 255.255.255.0 172.5.1.5 NaN
>> site_routing_data[1]
circuit errors route site mask next_hop error
0 FTTC None 10.10.1.0 Manchester 255.255.255.0 172.10.1.6 NaN
1 FTTC None 10.10.2.0 London 255.255.255.0 172.10.1.7 NaN
2 FTTC None 10.10.3.0 Birmingham 255.255.255.0 172.10.1.8 NaN
3 FTTC None 10.10.4.0 Sheffield 255.255.255.0 172.10.1.9 NaN
我想将这两个合并在一起,但是只替换表0中任何具有circuit列无值的记录。决赛桌看起来像
circuit errors route site mask next_hop error
0 MPLS None 10.10.1.0 Manchester 255.255.255.0 172.5.1.5 NaN
1 MPLS None 10.10.2.0 London 255.255.255.0 172.5.1.5 NaN
2 FTTC None 10.10.3.0 Birmingham 255.255.255.0 172.10.1.8 NaN
3 MPLS None 10.10.4.0 Sheffield 255.255.255.0 172.5.1.5 NaN
谢谢
答案 0 :(得分:1)
这应该有效:
df.loc[df.circuit.isnull(), df.columns] = df1[df1.columns]
