Question

I have 2 pandas dataframes. I am trying to update df with values from df2 based on matching index's. 

df
    Url_Sub_Fld     ip
0   tel             na
1   li              na
2   192.22.25.26    192.22.25.26

df2
   Url_Sub_Fld
1  test_string

Desired output: 

df
    Url_Sub_Fld     ip
0   tel             na
1   test_string     na
2   192.22.25.26    192.22.25.26
