In what situations can errors occur during program execution in Python?

Runtime errors in Python programs (exceptions) can occur in the following situations:

• Division by zero (ZeroDivisionError).
• Accessing a non-existent element in a list or dictionary (IndexError, KeyError).
• Attempting to use a variable that has not been defined (NameError).
• Type errors, such as adding a string and a number (TypeError).
• File operation errors, for example, if a file is not found (FileNotFoundError).
• Errors when working with networks, databases, and other external resources.

Example:

x = 10
print(x / 0)  # ZeroDivisionError
