Concept

When an error occurs, or exception as we call it, Python will normally stop and generate an error message

But this is not expected in Real Life Application, So these exceptions can be handled using the try, except statement.

Code

Example 1:

x = 10

if x == 10:
raise ValueError
elif x == 20:
raise KeyboardInterrupt
elif x == 30:
raise Exception("My Choice")
else:
print("All Okay")

Output:

Traceback (most recent call last): File "./prog.py", line 4, in ValueError
