You're wrong.  Compare:

    [pjb@kuiper :0.0 web]$ python
    Python 2.7.3 (default, Jan  2 2013, 13:56:14) 
    [GCC 4.7.2] on linux2
    Type "help", "copyright", "credits" or "license" for more information.
    >>> "abc"+2
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    TypeError: cannot concatenate 'str' and 'int' objects
    >>> 


with:

    [pjb@kuiper :0.0 tmp]$ cd /tmp ; cat a.c && gcc -o a a.c && ./a
    #include <stdio.h>
    int main(){
        printf("%s\n","abc"+2);
        return 0;
    }
    c
    [pjb@kuiper :0.0 tmp]$ 



What you mean is that Python is a late STRONGLY typed programming
language, while C is a early WEAKLY typed programming language.

Other languages are even more STRONGLY late typed programming languages
(eg Common Lisp).   There are also good early strongly typed programming
language like Haskell.   But strongly late dynamically typed programming
languages are probably better for mission critical systems, since they
can adapt dynamically the type of the values at run-time, instead of
crashing.
