Here are some of the steps that you can follow to optimize a nested if...elif...else.1. Ensure that the path that'll be taken most is near the top. This ensures that not multiple conditions are needed to be checked on the most executed path.2. Similarly, sort the paths by most use and put the conditions accordingly.3. Use short-circuiting to your advantage. If you have a statement like:if heavyOperation() and lightOperation():Then consider changing it toif lightOperation() and heavyOperation():This will ensure that heavyOperation is not even executed if lightOperation is false. Same can be done with or conditions as well.4. Try flattening the ... Read More

Python cannot iterate over an object that is not 'iterable'. The 'for' loop construct in python calls inbuilt functions within the iterable data-type which allow it to extract elements from the iterable.Since non-iterable data-types don't have these methods, there is no way to extract elements from them. And hence for loops ignore them.
HTML5 applicationCacheIt can be understood by an example that a web application is cached, and accessible without a connected internet. Application cache has some advantages: users can use the application when they're offline, cached resources load faster and reduced server load. Browser cache Web browsers use caching to store HTML web pages by storing a copy of visited pages. After that, the copy is used to render when you visit that page again
Built-in browser for Android will not give you accurate GPS location for security reasons. Test it with different web browsers that would need permissions to get the accurate location from GPS when installed.After switching GPS off, the data is received with < 10 meters accuracy.Do not use Android Browser for websites, if you want to get GPS location with high accuracy.50 meters precision can be seen for Safari browser if tested for iPhone with wifi switched off. Yes, the accuracy is lesser.
For responsive design, you do not have to use user-scalable=no. Use it only if you want your application to look more like a native app.Zooming is a key feature for accessibility and you need to keep that in mind. You can control that users won't break your design if they zoom in. If you are doing responsive and your design breaks when zooming in, then you're not doing it right.If you totally need to use it, then keep in mind that zooming is an important accessibility feature that is used by many people.

Python has an amazing graph plotting library called matplotlib. It is the most popular graphing and data visualization module for Python. You can start plotting graphs using 3 lines! For example, from matplotlib import pyplot as plt # Plot to canvas plt.plot([1, 2, 3], [4, 5, 1]) #Showing what we plotted plt.show() This will create a simple graph with coordinates (1, 4), (2, 5) and (3, 1). You can Assign labels to the axes using the xlabel and ylabel functions. For example, plt.ylabel('Y axis') plt.xlabel('X axis') And also provide a title using the title ... Read More

Session StorageThe Session Storage is designed for scenarios where the user is carrying out a single transaction but could be carrying out multiple transactions in different windows at the same time.Local StorageThe Local Storage is designed for storage that spans multiple windows and lasts beyond the current session. In particular, Web applications may wish to store megabytes of user data, such as entire user-authored documents or a user's mailbox, on the client side for performance reasons.HTML5 introduces the localStorage attribute which would be used to access a page's local storage area without no time limit and this local storage will ...
