Question

df=pd.DataFrame[columns='one','two','three']

for home in city:
    adres= home
    for a in abc: #abc is pd.Series od names
        #here i want to add values - adress and a , but my dataframe have 3 columns, i will use only 2 here
         df.loc[len(df)]= [adres, a, np.nan]
          print(df)

one, two, three
alabama, flat, NaN

我认为您正在寻找类似的东西：

for i in range(1):
    df.loc[i,['one','two']]=['adress','a']
print(df)

---

      one two three
0  adress   a   NaN
