What is runtime error in Python? Provide an example

If the program is syntactically correct means there are no syntax errors in the program the python interpreter will execute the program. But if the program exits unexpectedly then there exists a run-time error in the python program.

For Example:-

Accessing a list element which does not exists. divide by 0. Accessing a file which does not exists. Performing operation on incompatible types.

For ex:-

my_list=[1,34,7,3,7,8]

print (my_list[6])

This code will produce run-time error.
