python dictionary Posted: 27 Sep 2017 09:00 AM PDT An item in a dictionary is a key/value pair. You can think of a dictionary as an associative array (known in some other languages as an “unordered map,” “hash table,” or “hash”). Keys in a dictionary may be of different types, but they must be hashable. Values in a dictionary are arbitrary objects and may be of any type.

python for Posted: 26 Sep 2017 09:00 AM PDT Python for statement repeats execution of a statement, or block of statements, controlled by an iterable expression. The statement or statements that make up the loop body execute once for each item in iterable (unless the loop ends because of an exception or a break or return statement)

python while Posted: 26 Sep 2017 09:00 AM PDT Python while statement repeats execution of a statement or block of statements, until the loop condition is true. Once the loop body finishes executing, Python evaluates the loop condition again from the top to check whether another iteration should execute. This process continues until the loop condition is false, at which point the while statement ends.

python if Posted: 26 Sep 2017 09:00 AM PDT Often, you need to execute some statements only when some condition is true. Or in some cases you would need to execure different blocks of code based on a condition. The compound statement if â€"comprising if, elif, and else clausesâ€"lets you conditionally execute blocks of statements.

python with Posted: 26 Sep 2017 09:00 AM PDT Python with statement is used when you want to execute a block of code based on another operation. For example you need to open a file, for manipulating the file, then close it after you have worked with the file. In this case, python with is used to make sure that the file is closed after processing the file.

python string Posted: 26 Sep 2017 09:00 AM PDT Python String objects (byte strings, as well as text, AKA Unicode, ones) are immutable: attempting to rebind or delete an item or slice of a string will raise an exception. The items of a string object (corresponding to each of the characters in the string) are themselves strings of the same kind, each of length 1.

python list Posted: 26 Sep 2017 09:00 AM PDT A Python list is a mutable ordered sequence of items. The items of a list are arbitrary objects and may be of different types. To denote a list, use a series of expressions (the items of the list) separated by commas (,), within square brackets ([]); if every item is a literal, the whole assembly is a list literal. You may optionally place a redundant comma after the last item. To denote an empty list, use an empty pair of brackets

Python Basics - Setting up your Python Development Environment Posted: 25 Sep 2017 09:00 AM PDT The first decision you need to make is which version to download. The Python 2.7 or the Python 3.x. If you are a beginner and you are just starting to learn Python, then you should download 3.x. On the other hand, if you need to work on some legacy Python based application which depends on older libraries that cannot be ported, then you are better off with 2.7. But moving forward, there will not be any new releases on 2.7 Python. Eventually all have to migrate to 3.x version which is improved and most of the libraries are porting to the newer version. So Just go with version 3.x. Download the right release based on whether you are using Windows, Linux or Mac. Just download and install it in the default location.

Data Analytics - Which programming language to learn. R vs Python Posted: 23 Sep 2017 09:00 AM PDT Often people ask which one is better to learn? R or Python. Python is better for for data manipulation and repeated tasks, while R is good for ad hoc analysis and exploring datasets. For example, take text analysis, where you want to deconstruct paragraphs into words or phrases and then identify patterns. In this use case R is better suited and makes it simple. On the other hand, take for example, pulling the data, to running automated analyses over and over, to producing visualizations like maps and charts from the results then Python is better suited.

10 Best Smartphones under Rs 20,000 in India (2017) – Best Gadgetry

Sharang SharmaFebruary 4, 20170

Which is the best phone under 20,000 in India?

If a phone under Rs 20,000 is what you’re looking for, let us help you a little by handpicking the 10 best phones under Rs 20,000 for this month available in India. We’ve considered the specs, as well as the brand value and after sales service to give you the best phones 20k can get you. Also, all these phones support 4G LTE networks, so this list can be also considered for the best 4G LTE phones under Rs 20,000 in India.

This budget can get you features like 4GB RAM, 64GB storage, Snapdragon 820 processor and more. No, they won’t lag, hang or freeze up on you with those specs and will let you play the latest games at max settings without trouble, click great selfies and what not. Hopefully, most of them should get updated to Android 7.0. Also, read more about the camera specifications for these phones at the bottom of the post.

Not to confuse you with the camera specs listed above. We’ve listed the specs as (megapixels),(aperture), (sensor size). Generally speaking, bigger the aperture and sensor size, better is the camera. Which means smaller number in the denominator, the bigger the aperture or sensor size is. For example, f/1.9 is a bigger aperture and than f/2.0. Also 1/2.2″ is a bigger sensor than, say, 1/2.6″. A bigger aperture camera performs much better in low light situations and produces sharper images.
