You can split and explode:

(df.assign(Q2=df['Q2'].str.split(', '))
   .explode('Q2')
)

output:

   user_id Q1 Q2  Total Traffic(MB)
2        3  1  4          261.11860
3        4  8  3          179.18564
4        5  2  2          351.99208
4        5  2  3          351.99208
4        5  2  4          351.99208

@alexsmolyakov note that the resulting Q2 column is of type string, you might want to convert to int using `astype(int)` – mozway Oct 06 '21 at 16:02
