Q: A data analyst is tagging a number in the 2020 sales dataset of their organization with a certain variable. What variable name makes use of the proper syntax?
- -sales-2020
- 2020_sales
- sales_2020
- _2020sales
Explanation: “sales_2020” is the name of the variable, and “500000” is the value that has been allocated to it in this case. It is usual practice to use the underscore character (_) to separate words in variable names, which makes the names easier to read. The use of snake case is another name for this behavior. When assigning, the equal symbol (=) is often used.
