## Question

Asked By – Roman

I have constructed a condition that extract exactly one row from my data frame:

```
d2 = df[(df['l_ext']==l_ext) & (df['item']==item) & (df['wn']==wn) & (df['wd']==1)]
```

Now I would like to take a value from a particular column:

```
val = d2['col_name']
```

But as a result I get a data frame that contains one row and one column (*i.e.* one cell). It is not what I need. I need one value (one float number). How can I do it in pandas?

**Now we will see solution for issue: How to get a value from a cell of a dataframe? **

## Answer

If you have a DataFrame with only one row, then access the first (only) row as a Series using `iloc`

, and then the value using the column name:

```
In [3]: sub_df
Out[3]:
A B
2 -0.133653 -0.030854
In [4]: sub_df.iloc[0]
Out[4]:
A -0.133653
B -0.030854
Name: 2, dtype: float64
In [5]: sub_df.iloc[0]['A']
Out[5]: -0.13365288513107493
```
