Pyvenv is the standard tool for creating virtual environments, and has been part of Python since Python 3.3. Starting with Python 3.4, it defaults to installing pip into all created virtual environments; virtualenv is a third party alternative (and predecessor) to pyvenv. Getting and Installing MacPython¶. Mac OS X 10.8 comes with Python 2.7 pre-installed by Apple. If you wish, you are invited to install the most recent version of Python 3 from the Python website (https://www.python.org).

In this video, we cover the OS module with Python 3. The main purpose of the OS module is to interact with your operating system. The primary use I find for it is to create folders, remove folders, move folders, and sometimes change the working directory. You can also access the names of files within a file path by doing listdir(). We do not cover that in this video, but that's an option. The os module is a part of the standard library, or stdlib, within Python 3.

For example, a base of 4 with an exponent of 3 means that 4 is multiplied by itself 3 times, as in 4 x 4 x 4. An exponent is normally shown as a superscript number to the right of the base, but there is a different way to type exponents in Excel. When you enter a large exponent in Excel using the Base^Power formula, Excel displays it in scientific notation, as exponential notation. For example 10^100 appears as 1E+100. Ten to the power of 100 expressed in scientific notation is 1E+100. Best Answer: Using the superscript will not result in Excel parsing the string as 'exponential'. That is the function of the '^' symbol, which in Excel equates to any other arithmetic symbol such as +, -, /, *, etc. How to Do Exponents in Excel on PC or Mac. This wikiHow teaches you how to use a formula to calculate a power exponent's exact numeric value in an Excel spreadsheet, using a computer. Open Microsoft Excel on your computer. Find the Excel. Excel exponent shortcut. MS Excel 2011 for Mac: Create a superscript value in a cell This Excel tutorial explains how to create a superscript value in a cell in Excel 2011 for Mac (with screenshots and step-by-step instructions).

This means that it comes with your Python installation, but you still must import it. Sample code using os: import os All of the following code assumes you have os imported. Because it is not a built-in function, you must always import it. It is a part of the standard library, however, so you will not need to download or install it separately from your Python installation. CurDir = os.getcwd() print(curDir) The above code will get your current working directory, hence 'cwd.'

To make a new directory: os.mkdir('newDir') To change the name of, or rename, a directory: os.rename('newDir','newDir2') To remove a directory: os.rmdir('newDir2') With the os module, there are of course many more things we can do. In many scenarios, however, the os module is actually becoming outdated, as there is a superior module to get the job done. We will get to those soon enough. It is still a good idea to at least know some of the basics of the os module.

I especially like to use it to create directories. If you ever create a setup.py file, the creation of directories and the placing of files within them will be essential. The next tutorial.
