Question

To display the 3rd , 4th and 5th columns from the 6th to 9th rows of a dataframe DF , you can write ....
​

Answer 1

Answer:

Explanation:

DF.loc[6:9,3:5]

The answer will not be DF.iloc[6:10,3:6] because iloc uses default index, so the 6th value is at default index 5.

Answer 2

To fetch the data from the given locations, the following syntax is used.

DF.iloc[6:10, 3:6]

Explanation:

• We can use the loc() and iloc() functions to access columns with Pandas DataFrame.

• The first argument ( : ) signifies the rows we'd like to index, and therefore the second argument (Grades) lets us index the column we would like.
• The semicolon returns all of the rows from the column we tend to specify.

• The same result may also be obtained using the blog function. iloc arguments need integer-value indices rather than string-value names.

• In the iloc function 1st, we specify the range of rows i.e. 6 to 10 as 6:10 then after the comma, we should mention the columns as 3:6.

Hence, the DF.iloc[6:10, 3:6] command will display the 3rd, 4th and 5th columns from the 6th to 9th rows of a data frame DF.
