We create high quality technical contents for everyone in the form of Video, Article and Tutorials. Our focus is on Python and Raspberry Pi
We are a group of self-taught programmers who have developed coding skills over the years. We and Python (of course the programming language) are friends since a decade. We are experienced in working on numerous projects starting from very basic to highly complex ones. Python has spilled out of our professional life into our hobby and creative space.
Python For loop runs over a fixed sequence and various operations are performed under that particular range. Python’s for loop is part of a definite iteration group. In this comprehensive tutorial, you will understand every component to build a for loop and how quickly and efficiently implement them in Python. A developer or a programmer can choose to go with a for loop
The ternary operator aims at reducing multiple lines of if-else complexity into a single line. The Ternary operator works upon, where the result of an expression (conditional expression) depends on the True or False value. Bottom line – Consolidate (or condense) multi line expression in one line. If-else can be re-written in one line using the ternary operator.
Python if-else statement is a part of control structures (sometimes also known as Python flow control). Python if statement helps in making decisions in the program. This is probably the simplest yet most frequently used in Python for decision making. Python’s if-else statement works by evaluating a condition and subsequently making the decision. If a condition is met then execute a certain portion of the code
The literal_eval safely evaluate an expression node or a string containing a Python literal or container display. The string or node (a file) provided may only consist of the following Python literal structures: strings, bytes, numbers, tuples, lists, dicts, sets, booleans, and None. Python literal_eval is a function defined in “ast” class of built-in class library. The “ast” expands to Abstract Syntax Tree.
