Add percentage python

Like the most programming languages, Python too provides a mechanism to format a string. However, Python also has an alternate way for string formatting via the format function. It is a pretty old style and will remind you of the C programming language.

It signifies whether to substitute a number or a string. The primary problem with the C printf style formatting is that it limits the parameters to be passed. It was one of the newest features which got introduced in Python 3 for simplifying string formatting. It used a mini-language that provided ease of use and more options. Please note that its creators also ported it for Python 2.

It replaces the first occurrence of curly brackets with the value provided as a parameter to the format function. See another example to discover a potential difference between the string. It is quite evident from the above examples that the format function completely frees you from hard-coding the type of data to print and lets you focus on the formatting.

Percent means per hundred. See the other answers for the difference between integer and float division. FWIW, in Python 3.

This is because division works differently in that version. Active Oldest Votes. Is float 1 really more pythonic than 1. TobiasKienzler, I do not know, if it's more pythonic. At least it is something you stumble over while reading the code.

I think with Python 3 and real division by default this irritation is gone. I wonder why Guido didn't implement real division from the very start TobiasKienzler Probably because in earlier times, Python was closer to C than nowadays. In Python 2, I'd use 1. IMHO it's less obtrusive than the former and not as subtle as the latter.

Little bit "less convenient", but, yes! This is the best answer because it doesn't require a multiplication by Rather it takes advantage of the fact that format already knows how to print percentages!

It only takes a minute to sign up. I am using seaborn's countplot to show count distribution of 2 categorical data. Fine it works but I want the percentages to show on top of the bars for each of the plot. Please how do I do it? I have made edits based on the comments made but I can't get the percentages to the right of horizontal bars.

This is what I have done. You can move the texts around by changing the formula for x and y. For example, to place them on top:. Here is a general guideline for annotating axes. Sign up to join this community. The best answers are voted up and rise to the top.

Is there some other tweak fixing this? Can you be specific about what "didn't work"? If you look at the codeyou'll see that all countplot is doing is making a barplot with a len estimator and the same variable used for x and yso it's not obvious to me what your problem might be.

I should have been more specific, sorry for my stupidity I currently can't replicate the problem, so never mind. The example above does not work for me, somehow it plots a flat distribution whereas df is correctly populated with the Poisson samples.

Using 0. To be very honest, more than that, having a percentage option right within countplot would clear this issue once and for all, and given the number of entries on stackoverflow, it'd be great :.

As an OSS project maintainer myself, I definitely know how annoying these requests can be. It is not so obvious because different people will want different behaviors in the context of hue nesting and faceting. However it should always be possible for people to make the plot they want by defining the heights and using barplot. I would be happy to advise but as stated above, it is impossible to know what your problem is from saying "it does not work for me".

I'm having trouble reproducing mwaskom 's original response with my own dataset. Can you elaborate? Furthermore, I'm having trouble porting this to a Facetgrid which works great with countplot, just don't have proportions. Right, sorry for the confusion - like the OP, I want a "countplot" with percentages rather than raw counts. I'm trying to access this functionality through barplot as you recommended, but as described, I have a few fundamental questions about the workflow.

Email Required, but never shown. The Overflow Blog. Featured on Meta.This is a very old post. The Pandas API has matured greatly and most of this is very outdated.

This remains here as a record for myself. When I first started using Pandas, I loved how much easier it was to stick a plot method on a DataFrame or Series to get a better sense of what was going on.

However, I was not very impressed with what the plots looked like. This was a problem for me, as I ended up spending way too much time trying to make small edits and not enough time working on the code I was trying to visualize. One thing in particular bugged me.

I could find no easy to understand tutorial on annotating a bar chart on StackOverflow or any other site. MPL had some documentation, but it was too confusing for me at the time. I spent a lot of time trying to figure out how to put some text right above my bars.

Since I would have loved to see a snippet of code to help me in my journey, I thought I would throw it together in a brief post so others could use my workaround. I warn you, it is not the most elegent solution, I am sure, but it worked for me when I needed to demonstrate the insight I had gained from a Healthcare Access and Utilization Survey made up mostly of CHIS questions to people in my department, my director, and her bosses.

I love this data set because I am in the middle of book five of Game of Thrones, which provides a good amount of domain familiarity to enable jumping in easier. The image above is the output from the Jupyter notebook. I think it is super clear and gives a lot of information about where the battles were fought.

However, I am very parital to horizontal bar charts, as I really think they are easier to read, however, I understand that a lot of people would rather see this chart implemented in a regular bar chart.

So, here is the code to do that; you will notice that a few things have changed in order to create the annotation. I play around with the mpl. They are never exactly where they need to be, which often means moving thigs around a hair here and. You can add or subtract, which means you can also do this:. If you are like me, often you like to isolate a categorical value in one column and see what the rest of the dataframe looks like in light of that.

It is a simply way of drilling down, but a percentage really would not be as appropriate as a count. Here is an example of using a count rather than a percentage:. You can also just project a couple columns from those that lost to compare a couple of values; I think bar charts are great for this purpose.

I am not sure what the best way would be do accomplish this, but here is my implementation:. I really dislike tilting my head to one side to try and read what it says! Also, it is easy to rename the columns! I did not realize how simple it was, which makes me feel silly. I hope this is helpful for anyone out there trying to create little annotations for their visualizations. I feel like this is just a little bit of extra work but it keeps me from having to write JavaScript, which is worth a little copy paste action.

Here is a link to the notebook on my GitHub if you are interested in playing with it a bit more.
