Step 1
Explain this type of error.
Answer
A ZeroDivisionError is a type of runtime error that occurs when a program attempts to divide a number by zero. This is an illegal operation in mathematics and programming, as division by zero is undefined.
This error typically manifests when the program is executed and the specific line of code requesting the division is reached. The error serves as an indication that there is a logical flaw in the program, often suggesting that the code needs to include a check to ensure the divisor is not zero before performing the operation.
It can occur intermittently, particularly when user input is involved; for instance, if a user enters a value of zero that is then used as a divisor.
