Here's the implementation source for the same. Note: In Python 3.7, Constant folding was moved out from peephole optimizer to the new AST optimizer with some change in logic as well, so the fourth snippet doesn't work for Python 3.7. You can read more about the change here....
In the process of learning Express.js, so far, we have seen ‘What is Express js? its core features, and why we should use it. Moving ahead, we will have a look at what the code looks like in Express. How does the code look like in Express.js? In the below screenshot, we can...
represent parenthetical grouping e.g., python allows us use indentation instead although this might not work too great if we had multiple levels involving lots of tiny sub-sections as there just wouldn't be enough visual clarity. what are the benefits of using parentheses in programming languages...
API: The intermediary that connects the two in a well-documented, predictable way Think about a restaurant. If customers all walked into the kitchen to order their favorite dishes, chaos would ensue. In this scenario, the API provides a menu (documentation) that lists all the services (dishes...

Should I expect a change in Amazon CloudFront performance when using IPv6? Are there any Amazon CloudFront features that will not work with IPv6? Does that mean if I want to use IPv6 at all I cannot use Trusted Signer URLs with IP whitelist? If I enable IPv6, will the IPv6 address ...
Phew! What does this mean for IWYU? IWYU links to the ClangDriverlibrary, and so would nominally get the exact same policy by default:CLANG_RESOURCE_DIRrelative to theinclude-what-you-useexecutable. This means the IWYU build would have to create the resource dir in its build tree, and als...
GPIO pins have multiple names; the first most obvious reference is their “physical” location on the GPIO. Starting at the top left of the GPIO, and by that we mean the pin nearest to where the micro SD card is inserted, we have physical pin 1 which provides 3v3 power. To the right...
Now what does the FT say? File "functional_tests.py", line 42, in test_can_start_a_list_and_retrieve_it_later any(row.text == '1: Buy peacock feathers' for row in rows) AssertionError: False is not true Slightly cryptic. We can use the line number to track it down, and it tu...
In the end, lots of things may have to happen before the bot can reply to the user. So, there are lots of points where things may go wrong. How does one trace an error or a latency, when the bot logic may be a “black-box”? How can we “see” inside the execution?
