What are the reasons for exceptions in Python programs?

Exceptions in Python occur when an error happens during program execution that the interpreter cannot handle in the usual way. The main causes of exceptions:

• Logic errors in the program (e.g., division by zero).
• Attempting to access a non-existent element (index or key).
• Data type errors (e.g., adding a string and a number).
• Input/output errors (e.g., file not found).

Example:

x = 10 / 0  # will raise ZeroDivisionError
