Differentiate between 'w' and 'a' file modes in Python.
\[ \begin{array}{|c|c|} \hline \textbf{File Mode} & \textbf{Description} \\ \hline 'w' & Opens the file for writing. If the file exists, its content is erased. \\ 'a' & Opens the file for appending. Data is added to the end of the file. \\ \hline \end{array} \]
The SELECT statement when combined with \(\_\_\_\_\_\_\) clause, returns records without repetition.
print(16 * 5 / 4 * 2 / 5 - 8)
myStr[:4] extracts the first 4 characters, which are "MISS".myStr[-5:] extracts the last 5 characters, which are "SIPPI"."#" in between, resulting in "MISS#SIPPI".In SQL, the aggregate function which will display the cardinality of the table is \(\_\_\_\_\_\).
