Re: How to sort over dictionaries

The top-level object you are showing is a list [], not a dictionary {}. It has dictionaries inside of it though. Do you want to sort the list? Python's sorted() function returns a sorted copy of a sequence. Sorted() has an optional argument called "key". Key accepts a second function which c

Re: Question about floating point

Hi Frank, One difference is that, in order to carry out the instructions embodied in the first example, the computer has to perform arithmetic. And it adds the binary approximation of 1.1 (which is very slightly wrong) to the binary approximation of 2.2 (which, again, is very slightly wrong). It t

Question about floating point

Hi all I know about this gotcha - x = 1.1 + 2.2 x 3.3003 According to the docs, the reason is that "numbers like 1.1 and 2.2 do not have exact representations in binary floating point." So when I do this - y = 3.3 y 3.3 what exactly is happening? What is 'y' at this point?

Re: virtualenv and ubuntu

Hi, If you install with sudo it is installed for 2 users i.e current logged in as well as root. So if one login as root can use the installed "env". But if you install it with pip it will be used by the current logged in user. In my opinion, use pip to install virtualenv On Tue, Aug 28, 2018 at
