Nzec exception in python

NZEC stands for “Non-Zero Exit Code” exception in Python. When a programme ends with a non-zero status code, which denotes that an error or exception occurred during execution, it often happens. This exception is frequently seen in coding competitions or on websites like CodeChef or HackerRank.

Here’s an example that can trigger the NZEC exception:

# Example 1: Division by zero

try:
    a = 10
    b = 0
    result = a / b
    print(result)
except ZeroDivisionError:
    print("Error: Division by zero")

In the above example, the program tries to divide the variable ‘a’ by zero, which raises a ‘ZeroDivisionError’ exception. Since this exception is not handled properly, the program will exit with a non-zero status code, resulting in an NZEC exception.

To avoid the NZEC exception, you can handle the exception appropriately, like this

# Example 2: Handling the exception

try:
    a = 10
    b = 0
    result = a / b
    print(result)
except ZeroDivisionError:
    print("Error: Division by zero")
except Exception as e:
    print("Error:", e)

In the modified example, we catch the ZeroDivisionError and print a custom error message. Additionally, we have a generic Exception block that can catch other exceptions and display a generic error message. Handling the exception prevents the program from exiting with a non-zero status code, avoiding the NZEC exception.

It’s important to note that the specific cause of an NZEC exception may vary depending on the context and platform where the code is executed. Therefore, it’s recommended to carefully analyze the error message and the code logic to identify the root cause of the exception and handle it accordingly.
