what's the use of "del" in python3?

Question

I mean we can just not write the variable and its value rather than defining a variable and then using "del" and then defining the var again?

Answer 1

Risko here is a bit of reading material... if you preset the variable just incase a not input then the del would not execute but if you are wanting to use a direct input the preset variable will be deleted and replaced with the new variable...
