![]() If you want to create and compress stickers under 500 KB take a look at the iMessage Panda sticker example on Github. Only Interned Explorer does not support the format yet.Īpple added animated stickers to iMessage with the release of iOS 10. Binary transparency without any workarounds! Is it safe to use animated PNG?Įxcellent question! Chrome, Firefox, Safari and now Microsoft Edge all support APNG. With TinyPNG the background becomes transparent again. Still need to support Internet Explorer 6? It normally ignores PNG transparency and displays a solid background color. ![]() Is it supported everywhere?Įxcellent question! The files produced by TinyPNG are displayed perfectly on all modern browsers including mobile devices. I have excellent eyesight but can’t spot the difference either! Use the optimized image to save bandwidth and loading time and your website visitors will thank you. In the above image the file size is reduced by more than 70%. The result better PNG files with 100% support for transparency. All unnecessary metadata is stripped too. By reducing the number of colors, 24-bit PNG files can be converted to much smaller 8-bit indexed color images. This is a great starting point: Black Friday Sales Project.File size 57 KB vs Shrunk transparent PNGĮxcellent question! When you upload a PNG (Portable Network Graphics) file, similar colors in your image are combined. Start participating in competitions to showcase your skills. If you come across any more such Pandas functions, do comment and I’ll be happy to learn and share! As I mentioned earlier this comes in especially handy in hackathons when time is of the essence. The Transform function is super useful when I’m quickly looking to manipulate rows or columns. So, we can use either Apply or the Transform function depending on the requirement. This just manipulates a single row or column based on axis value and doesn’t manipulate a whole dataframe. This feature is not possible in the Transform function. The apply function sends a whole copy of the dataframe to work upon so we can manipulate all the rows or columns simultaneously. This is what the output looks like using the Apply function: Let’s do it! Step1: Import the libraries and read the dataset The first approach is using groupby to aggregate the data then merge this data back into the original dataframe using the merge() function. I’ll implement both of them in this article.Īpproach 1: Using Groupby followed by merge(): There are multiple approaches to do this: This helps us in creating a new feature for the model to understand the relationship better. We would like to know what is the mean purchase amount of each user. We can see that each user has bought multiple products with different purchase amounts. Here, we have a dataset about a department store: Let’s understand the importance of the transform function with the help of an example. As the name suggests, we extract new features from existing ones. Transform comes in handy during feature extraction. Why is Python’s Transform Function Important? ![]() This is the dataframe we get after applying Python’s Transform function:Ģ. Let’s say we want to multiply 10 to each element in a dataframe: That was a lot to take in so let me break it down using an example. This dataframe has the same length as the passed dataframe. Python’s Transform function returns a self-produced dataframe with transformed values after applying the function specified in its parameter. What is the Transform Function in Python?
