In Python, you can specify an else statement to a for loop or a while loop. The else block is executed if a break statement is not used.
Python also supports nested conditional logic, meaning that you can nestif,elif, andelsestatements to create even more complex programs. To nest conditions, indent the inner conditions, and everything at the same level of indentation will be run in the same code block: ...
As you’ve seen here, theloop-elseconstruct can be explained in just about no time at all, but there’s still a large amount of confusion about its meaning all over the web. This is hardly surprising given that formulaic explanations such as the one above don’t reveal any of the under...
just python, from what I can tell. That's my feature request: treat installing python the same as installing any other package, downgrade it on command as specified in the file, and keep the python version that's being used separate from all the ...
So far in Python I've almost hated the 'else' of the 'for' loops: - I have problems to remember its meaning; - It gives me little problems when I later want to translate Python code to other languages (and you always have to translate long-lived code). - I have used it only ...
Python has an unusual appendix to its looping structures: a “for” or “while” loop can also have an “else” clause. It took me a while to get it, but now it makes complete sense to me.

You just need to take the literal meaning of Optional that value may or may not be present and you have to code accordingly. This will think you what to do in case of value is not present like using a default value or throwing a proper error message. ...
For instance, we could write the code above like this without having any effect on its semantics (i.e. meaning): JavaScript var isRaining = true; if (isRaining) alert("Don't forget an umbrella!"); The new line and additonal indentation here is really handy — it helps us distinguish ...
