use reversed() function: It’s much more meaningful. Update: If you want it to be a list (as btk pointed out): Update: If you want to use only range to achieve the same result, you can use all its parameters. range(start, stop, step) For example, to generate a list [5,4,3,2,1,0], you can use the following: It may be less intuitive but as … Read more
I am trying to plot a histogram using the matplotlib.hist() function but I am not sure how to do it. I have a list and a list of names(strings). How do I make the probability as my y-value of each bar and names as x-values?
The simplest way to accomplish this is to put the input method in a while loop. Use continue when you get bad input, and break out of the loop when you’re satisfied. When Your Input Might Raise an Exception Use try and except to detect when the user enters data that can’t be parsed. Implementing Your Own Validation Rules If you want to reject values … Read more
It might be late but for anyone with the same issue the solution is using the method legend() for the corresponding ax not as for plt
You have to define which type of exception you want to catch. So write except Exception, e: instead of except, e: for a general exception (that will be logged anyway). Other possibility is to write your whole try/except code this way: in Python 3.x and modern versions of Python 2.x use except Exception as e instead of except Exception, e:
Installing libffi-dev and re-installing python3.7 fixed the problem for me. to cleanly build py 3.7 libffi-dev is required or else later stuff will fail If using RHEL/Fedora: or If using Debian/Ubuntu:
Here’s how I would do this: The setter didn’t work at the time we call Bar.bar, because we are calling TypeOfBar.bar.__set__, which is not Bar.bar.__set__. Adding a metaclass definition solves this:
Step 1: Install the dependencies Step 2: Run this command in your virtualenv
You can create subset of data with your condition and then use shape or len: Performance is interesting, the fastest solution is compare numpy array and sum: Code:
More code would be appreciated (specifically the ParamExample implementation), but I’m assuming you’re missing the __enter__ (and probably __exit__) method on that class. When you use a with block in python, the object in the with statement gets its __enter__ method called, the block inside the with runs, and then the __exit__ gets called (optionally with exception info if one was raised). Thus, if you don’t have an __enter__ defined … Read more
