Python is one of the most widely used programming languages. It’s getting a lot of popularity these days because of so many Python frameworks in IoT, Machine Learning, Deep Learning, and Artificial Intelligent space.
These Python Tutorials will help you in getting mastery over the Python Programming. The tips and tricks shared by us will enable you to write pythonic code with high performance, reusability, readability, and maintainability.
A program may need a directory at a particular filesystem path. Python’s directory-creation calls let you create one directory or create missing parent folders along the path. This article explains the os mkdir operation and shows how os.mkdir() and os.makedirs()…
Updating Python code that uses xrange() starts with knowing which Python version the code targets. In Python 2, xrange() provides an immutable integer sequence for loops, while Python 3 uses range() for that job. This article explains what xrange() did…
Making predictions with a Python model starts with understanding the result it returns. The predict() method applies a fitted model to input examples and returns an output based on the model and its task. I’ll explain how to read predict()…
Do you need the removed value, or should the original dictionary stay intact? The pop method returns the value it removes, while del removes the entry. The article compares those methods with a filtered copy and shows how pop handles…
Counting the frequency of each value in a Python list gives you a tally of repeated and one-off items. Python’s collections.Counter builds that tally from an iterable, storing each hashable value with its count. I’ll show how to build and…
Using category labels as features in Python starts with encoding them into a form a model can use. A one-hot encoding gives each category its own binary feature column. I’ll walk through encoding columns and checking how the fitted encoder…
When a Python calculation needs a particular kind of numeric representation, it helps to know what the built-in float provides. On standard builds, float uses double-precision binary floating point, while Decimal and Fraction offer other ways to represent values. This…
To convert an integer into a binary string, you need a way to express its value with the digits zero and one. Python can return that string with a 0b prefix or as binary digits without the prefix. I’ll compare…
Choosing a name for Python code starts with checking whether Python gives that name a special role. The keyword module lists strict keywords and checks whether a name is a keyword or a soft keyword. I’ll explain the difference between…
Working with a sequence of values in Python starts with choosing how to represent those values. The array module lets you create an array by choosing a type code and supplying starting values. This article demonstrates array operations and compares…
