Mar 3, 2025 · Variables store values and Python supports multiple data types. We can check the data type of a variable using type () and convert types if needed. In general, Operators are used to execute operations on values and variables. These are standard symbols used in logical and mathematical processes.

We can receive input from the user by calling the input() function. The input() function always returns data as a string. So, we’re converting the result into an integer by calling the built-in int() function. We can define strings using single (‘ ‘) or double (“ “) quotes.
