Python: Does finally needs a try-except clause?

Question

Suppose the following code.

try:
    some_code_1
except: # will it be called twice, if an error occures in finally?
    some_code_2
finally:
    some_code_3

Suppose an exception occurs in some_code_3. Do I need an extra try-except clause around some_code_3 (see below) or will the exception with some_code_2 be called again, which in principle could cause an infinite loop?

Is this saver?

try:
    some_code_1
except: # will it be called twice, if an error occures in finally?
    some_code_2
finally:
    try:
        some_code_3
    except:
        pass

Answer 1

Just give it a try:

try:
    print(abc) #Will raise NameError
except: 
    print("In exception")
finally:
    print(xyz) #Will raise NameError

Output: 
In exception
Traceback (most recent call last):
  File "Z:/test/test.py", line 7, in <module>
    print(xyz)
NameError: name 'xyz' is not defined

So no, it doesn't end up in an infinite loop
