It is reported that Africa’s first COVID-19 vaccine trial began on June 24 in South Africa. The vaccine, developed by Oxford University’s (UK) Jenner Institute, will inoculate 2,000 South Africans.

Researchers have now reported data from early (and small) clinical trials of four candidate COVID-19 vaccines.

So far, the data is positive. The vaccines appear

Latest iOS 14 beta offers more evidence of a 5.4-inch iPhone

iOS 14’s third beta contains more evidence that Apple has an iPhone with a 5.4-inch display on the way, 9to5Mac reports.

The reasoning is a little complicated, so bear with us. 9to5Mac is basing its hunch on iOS’s Display Zoom feature, which you can use to make your phone’s text, buttons, and icons bigger. Display Zoom works by pretending your phone has a smaller physical display, so if you’re using an iPhone 11 Pro Max with a 6.5-inch screen, Display Zoom shows the interface designed for the 5.8-inch display of the iPhone 11 Pro, essentially magnifying the elements.

How to reverse a string in Python

As there is no in-built function, if you want to know how to reverse a string in Python, you will need to use one of two McGyver techniques. Fortunately, these are still relatively straightforward and don’t take long at all to learn. Here’s what you need to know.

How to reverse a string in Python using slicing

The first way to reverse a string, is to use a slice that steps backward. Slices in Python let you return chunks of data from strings, tuples, and lists. This is useful if you ever want to get a few items from a

Open a CSV file in Python

A CSV file is a “comma-separated values” file. In plain English, this is a text file that contains an unusually large amount of data. More often than not, this is used in order to create databases of information, where each unit of data is separated by a comma. Hence the name!

Being able to manipulate, load, and store large amounts of data is a hugely beneficial skill when programming. This is particularly true in Python, seeing as Python is such a popular option for machine learning and data science.

Read on then, and we’ll explore how to read CSV files
