If you've used R or even the pandas library with Python you are probably already familiar with the concept of DataFrames. The difference between NROW() and NCOL() and their lowercase variants (ncol() and nrow()) is that the lowercase versions will only work for objects that have dimensions (arrays, matrices, data frames). I want to print the details of the students whose score is … We will use dataframe count() function to count the number of Non Null values in the dataframe. print 'iat =>', y.iat[2, 1] # prints iat => C 5. number of rows and columns in this dataframe. pandas.DataFrame.head¶ DataFrame.head (n = 5) [source] ¶ Return the first n rows..

You can imagine that each row has a row number from 0 to the total rows (data.shape[0]), and iloc[] allows selections based on these numbers.
