As the Py virtual machine executes the byte code line by line so it is interpreted. Languages Like C are compiled Languages.
For example:

For the following code we get this output:

print("Hello World")
print(a)

Hello World

Traceback (most recent call last): File "c:\PythonOm\pyTest.py", line 2, in print(a) ^ NameError: name 'a' is not defined

For a similar code in C "Hello World " will not even be printed we would get compile time error not run time error.
