Answer 1

You can use pd.concat() with axis=1, see docs

df_1 = pd.DataFrame([
  [1],
  [2],
  [3],
], columns=["a"])

df_2 = pd.DataFrame([
  [2, 7],
  [3, 6],
  [4, 5],
], columns=["b", "c"])

df_3 = pd.concat([df_1, df_2], axis=1)

print(df_3)

Result:

   a  b  c
0  1  2  7
1  2  3  6
2  3  4  5
