Which of the following codes will display the total number of rows in the DataFrame stud?
- print (len(stud.axes[0]))
- print (stud.len(0) )
- print (stud.len [axes=0] )
- print (len (stud.axes[row] )
Answer
print(len(stud.axes[0]))
Reason — The command stud.axes[0] gives access to the index labels along the 0th axis (rows) of the DataFrame stud. The len(stud.axes[0]) returns the length of this index label array, which corresponds to the total number of rows in the DataFrame stud.
