Is Python strongly or weakly typed? - amandio - Jul-10-2018

I'm a computers network studant from João Pessoa-Paraiba-Brazil, and I'm studying programming. Python is the programming language that we are atudying and in one of the exams that I made, there was a question saying "Python is strongly typed".

The teacher said this answer was wrong because Python is weakly typed. I believed the teacher, but I'm engaged in my studies, so after some time I decided to search about this and after a lot of search and interaction on forums about Python, I'm almost sure that this is a strongly typed language.

Python is strongly typed.
>>> a = 5
>>> b = '6'
>>> a + b
Traceback (most recent call last):
  File "<string>", line 428, in runcode
  File "<interactive input>", line 1, in <module>
TypeError: unsupported operand type(s) for +: 'int' and 'str'

Let's make a collection of TypeError, ValueError, InvalidOperation, etc.

In [68]: int('0.3')
---------------------------------------------------------------------------
ValueError                                Traceback (most recent call last)
<ipython-input-68-0d64588ae80e> in <module>()
----> 1 int('0.3')

ValueError: invalid literal for int() with base 10: '0.3'
