96 What does the “at” (@) symbol do in Python? @ symbol is a syntactic sugar python provides to utilize decorator, to paraphrase the question, It's exactly about what does decorator do in Python? Put it simple decorator allow you to modify a given function's definition without touch its innermost (it's closure).
In Python this is simply =. To translate this pseudocode into Python you would need to know the data structures being referenced, and a bit more of the algorithm implementation. Some notes about psuedocode: := is the assignment operator or = in Python = is the equality operator or == in Python There are certain styles, and your mileage may vary:
There's the != (not equal) operator that returns True when two values differ, though be careful with the types because "1" != 1. This will always return True and "1" == 1 will always return False, since the types differ. Python is dynamically, but strongly typed, and other statically typed languages would complain about comparing different types. There's also the else clause:

It appears you had Python 2 in mind when you answered this, because in Python 3 for key in my_dict.keys() will still have the same problem with changing the dictionary size during iteration.
