Consider following Python statements −a = 10 b = 5 a = a + b print (a) At the first instance, at least for somebody new to programming but who knows maths, the statement "a=a+b" looks strange. How could a be equal to "a+b"? However, it needs to be reemphasized that the...
Python x, y = 3, 8 if x = y: print(f"x and y are equal ({x = }, {y = })") Unlike the C example, this Python code gives you an explicit error instead of a bug.The distinction between assignment statements and assignment expressions in Python is useful in order to avoid ...

I still think we should add more tests for f-strings in clause headers and assert statements. For example: if (f"teaaaaaaaaaaaaaaaaaaaaaaaa{ expressioneeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee # comment }aast".contains('a') ): pass We now remove parentheses from: aaaaaaaaaaaaaa...
In your last lesson, you compared pass by value with pass by reference in C++. In this lesson, you’ll look at Python’s argument passing mechanism. Python doesn’t use either pass by value or pass by reference. It uses something called pass by…
