How to Compute Subtraction in Python Numbers can be subtracted using the - operator. Again, in the example below in Jupyter notebook, the minus is the operator and 2 and 10 are operands. >>> 2 - 10 -8 Of course, you can also subtract floating-point numbers: >>> 2.1 - 10.1 -8.0 ...
Intro to Programming: What Are Strings in Python? Dictionaries are also similar to lists. You separate these pairs by commas to ensure the Python interpreter understands where one pair ends and the next pair begins. Note that you put colons between the key and the value inside a pair. These...

Magic numbers are one of those bad practices in programming that have somewhat of a weird name. After all, folks generally like magic, so it’s unclear what’s so bad about them. Fortunately, today we’ll talk about what a magic number is and how to remove them from your programs. ...
Those numbers are really annoying. You should avoid creating magic numbers in your code.Declare a constant, with a meaningful name, and use that instead of a magic number.For example:const int PIN_ID = 1; doSomething(PIN_ID);is much better, and self-documenting, compared to:...
Scripts can be stored in iCloud now. Added support for opening external files (from other apps) in-place, using the document picker. Added “Open in…” menu support for opening Python scripts from other apps. If the sending app supports it, files are opened in-place (otherwise they’re...
So is is for reference equality and == is for value equality. An example to clear things up, >>> class A: pass >>> A() is A() # These are two empty objects at two different memory locations. False256 is an existing object but 257 isn'tWhen you start up python the numbers from...
Python 3.0 has simplified the rules for ordering comparisons: The ordering comparison operators (<, <=, >=, >) raise a TypeError exception when the operands don’t have a meaningful natural ordering. Thus, expressions like 1 < '', 0 > None or len <= len are no longer valid, and e....
The changes above are the main ones I’ve found useful when updating Python Morsels exercises over the last week. There are many more changes in Python 3.10 though. Here are a few more things I looked into, and plan to play with later: ...
