onsider the dataframe df. How would you access the element in the 1st row 3rd column
Question
Consider the dataframe df
.
How would you access the element in the 1st row 3rd column?
Solution
To access the element in the 1st row and 3rd column of a DataFrame df
in Python using the Pandas library, you can use either the .iloc
indexer or the .iat
indexer. Here’s how you can do it using both methods:
-
Using
.iloc
:element = df.iloc[0, 2]
-
Using
.iat
:element = df.iat[0, 2]
Explanation:
- The
.iloc
method is used for integer-location-based indexing, where the first argument is the index of the row and the second argument is the index of the column. Since Python uses zero-based indexing, the first row is indexed as0
and the third column as2
. - The
.iat
method is similar but is more efficient for accessing a single value at a specific position.
Both methods will give you the same result, which is the value in the 1st row and 3rd column of the DataFrame df
.
