The first of those comes with PEP 618, which adds an optional strict flag to the zip() function. If we set strict=True an error will be raised if both inputs to zip are not of an equal length.

Great ideas won’t go anywhere on their own. It’s tempting to fantasize about having freedom and earning a living with your business. But ideas that sound good in our minds don’t necessarily work in reality. So if you really want to act on your idea, the best thing you can do is to quickly test it out in the real world. That will increase your odds of real success.

The value of a physical retail infrastructure has been clear since Amazon made their largest acquisition ever, Whole Foods (* see addendum below for more on this). Brick and mortar stores have tremendous online value in addition to enabling true omnichannel commerce. Nothing matters more for an e-commerce company than marketing efficiency expressed either as gross margin $ payback period or the ratio of CAC to LTV. Brick and mortar stores significantly lower online CAC by improving marketing efficiency (higher click through rates, higher quality scores for ads). Consumers are more likely to trust a brand they have seen in the real world. Ironic in a world where “CAC is the new rent” that one of the best ways to lower your online rent, i.e. CAC, is to pay rent offline for physical stores. Brick and mortar stores also enable BOPIS (buy online pickup in store) and the in-store return of items purchased online, which consumers value. Economically, BOPIS will always be cheaper than same day delivery and large numbers of consumers are highly cost sensitive.

You want everything to be professional and seamless. I use Kajabi to host my courses. But again, all these popular platforms for hosting courses will do. No matter what you do, don’t get hung up on tools. It’s just like smartphones, they all have the same features. Just pick one you like.

I believe the biggest long term beneficiaries of Covid will prove to be category leading brick and mortar retailers. By this I simply mean brick and mortar retailers who have dominant share in a category — whether it be home improvement, general merchandise, electronics or any other retail category. Their destiny has likely changed forever. Many of the perceived Covid winners such as e-commerce, videogame and streaming media companies have simply been pulled a few years forward into a future that was inevitable. Their destiny did not change. The future for those businesses simply accelerated whereas the future for category leading “brick and mortar” retailers has changed dramatically as a result of Covid, more so than for any other business of which I can think. It is likely that food delivery and videoconferencing companies are also permanently advantaged due to Covid, but the change in ultimate outcome is not as extreme as I think it will be for category leading brick and mortar retailers.

Three dictionary methods dict.keys(), dict.values(), and dict.items() all return a different view of a dictionary. Now, a mapping attribute has been added to each of these view objects.

Said another way, long term steady state FCF will likely be the at the same level for many e-commerce, videogame and streaming media companies as it would have been before Covid. This is not to say that Covid did not increase their value; it did but primarily by pulling their financials forward a few years which obviously matters in a DCF. Whereas long term steady state FCF will likely be significantly higher for category leading brick and mortar retailers who had reasonably strong e-commerce businesses coming into Covid. Especially so for those category leading retailers who operate in inflationary categories where inventory turns are less important than they are in deflationary categories where e-commerce only companies have structural cost advantages due to faster inventory turns.

These changes show a commitment to the type annotation features of Python. The added clarity to our favorite libraries (and our own code) may leave an interesting long-term impact on the Python ecosystem.

Rather than blindly truncating mismatched data, the new strict argument allows us to control the behavior of zip — something that will save plenty of developers from a headache somewhere down the line.

The future was always going to be omnichannel. Pundits have been prematurely predicting this for many years, but it is finally happening. There is a strange belief in certain circles that the future will be e-commerce only and that brick and mortar stores have no value. This is strange because the worlds largest, most sophisticated e-commerce companies are all opening stores. Lots of stores. Amazon opened dozens of “Amazon Go” stores in 2019 and is reportedly planning on opening up to 3000 of these stores by 2021 in the United States alone. Amazon already has multiple store formats in the United States: Go, Whole Foods, Book Stores and others. In his 2017 letter to shareholders, Jack Ma wrote that “Commerce as we know it is changing in front of our eyes. ‘E-commerce’ is rapidly evolving into ‘New Retail.’ The boundary between offline and online commerce disappears as we focus on fulfilling the personalized needs of each customer.” Alibaba is rapidly opening several different store formats throughout China. JD is also rapidly opening stores. Wayfair has stores. Led by Warby Parker, most DTC branded startups have stores.

now in her first year of engineering at the University of Toronto, said that while using technology is “second nature” for her and her peers, she still wishes she had a better understanding of how to protect herself on the websites she learned to build.

You don’t need to create products or features that no one needs from the start. Just work on the customer experience. This may not sound like a very big deal at first, but a page that loads too long or a shopping cart that loops in an error can easily discourage a buyer.

Despite all of these advantages conferred by owning a physical retail infrastructure, most brick and mortar retailers were painfully slow to embrace e-commerce and omnichannel. An entire generation of management teams effectively ceded the future to Amazon because of objectively incorrect beliefs about e-commerce profitability and internal cultural issues. In some ways, the bursting of the bubble in 2000 was the best thing that ever happened to Amazon. The bursting of the bubble, the collapse in Amazon’s stock price and the aggressive way Amazon ran their business convinced most retail executives that e-commerce was unprofitable. In reality, Amazon’s US e-commerce business likely became significantly profitable more than 15 years ago, but they invested aggressively in new categories and new geographies which masked this fact for people doing superficial analysis.
