create a variable in Ruby

  my_variable = 7

This code creates a new variable named “my_variable” and assigns it the numerical value of 7. Variables are used to store information in programs which can be accessed and used in other parts of the program. When creating a new variable in Ruby, we use the equal sign (=) to assign a value to the variable. In this case, that value is the number 7. Variables can also be used to store strings (words), booleans (true or false), or special data types like hashes or arrays. Once a variable has been created, we can then use it in other parts of our program.
