@AnuragDabas I need to fecth the corresponding places as well — Gayathri K, Jun 08 '21 at 14:56
what do you mean by *'I need to fetch the corresponding places as well'*? — Anurag Dabas, Jun 08 '21 at 15:02
@AnuragDabas in this example I have to fetch only INDIA and USA. The name is ROSE and the condition is FALSE so I have to fetch the corresponding place. Pls look into the output snapshot once — Gayathri K, Jun 08 '21 at 15:04
try: `cond=(df['Name']=='Rose') & (df['Condition']=='Fail') & df['Place'].isin(['USA','India'])` finally `df[cond]` or `df.loc[cond]` — Anurag Dabas, Jun 08 '21 at 15:08
@AnuragDabas It can be anything X, Y , Z .. Not just USA , INDIA. based on the condition of column "Condition as FAIL" the corresponding value from the place column has be to fetched — Gayathri K, Jun 08 '21 at 15:14
have a look on the previous comment and read this line *I have to fetch only INDIA and USA* — Anurag Dabas, Jun 08 '21 at 15:26
@AnuragDabas The values in column "Place" is not constant.. It keeps changing — Gayathri K, Jun 08 '21 at 15:37

df[(df["Name"] == "Rose") & (df["Condition"] == "Fail")]

Output

   Name   Status  Place
0  Rose     Fail  India
1  Rose     Fail    USA
2  Rose     Fail      X

To fetch only Place column as a list

df[(df["Name"] == "Rose") & (df["Condition"] == "Fail")]["Place"].tolist()

Output

   ['India', 'USA', 'X']

The corresponding Places also has to be fetched – Gayathri K Jun 08 '21 at 14:58
Do you mean, you would like to have as output a list [India, USA] ? – YuserT Jun 08 '21 at 15:12
Based on the condition of ROSE , FAIL ... its corresponding value in the same row in the place column has to be fetched. It can be anything .. x,y.. not just india , usa.. – Gayathri K Jun 08 '21 at 15:16

The code above returns the PLACE column values (which can be anything not just india or usa) for the rows satisfying the (Rose and Fail) condition. – YuserT Jun 08 '21 at 15:19

Hey what if I am getting the Name column from the user. "Rose" should be from user input. all other things are same. @YuserT – Gayathri K Jun 09 '21 at 02:58
A code snippet of how you are getting the Name column from the user would be useful. – YuserT Jun 09 '21 at 08:13
