Python 3 is all-in on Unicode and UTF-8 specifically. Here’s what that means: Python 3 source code is assumed to be UTF-8 by default. This means that you don’t need # -*- coding: UTF-8 -*-at the top of .py files in Python 3. All text (str) is Unicode by default. Encoded Unicode text is represented as binary data (bytes).

Python is an interpreted, object-oriented, high-level programming language with dynamic semantics. Its high-level built in data structures, combined with dynamic typing and dynamic binding, make it very attractive for Rapid Application Development, as well as for use as a scripting or glue language to connect existing components together. Kolade Chris. In Python, you use the double slash // operator to perform floor division. This // operator divides the first number by the second number and rounds the result down to the nearest integer (or whole number). In this article, I will show you how to use the // operator and compare it to regular division so you can see how it works.

Where in other programming languages the indentation in code is for readability only, the indentation in Python is very important. Python uses indentation to indicate a block of code. These ( +=, -=, *= and /=) are called augmented arithmetic assignments. They correspond to the following methods: the i semantically means "in-place", which means that they modify the object (or reference in the case of numerics) without having to additionally assign them: foo += bar. foo = foo + bar.In the form shown above: <expr> is an expression evaluated in a Boolean context, as discussed in the section on Logical Operators in the Operators and Expressions in Python tutorial. <statement> is a valid Python statement, which must be indented. (You will see why very soon.) If <expr> is true (evaluates to a value that is “truthy”), then <statement> is …Data model — Python 3.12.2 documentation. 3. Data model ¶. 3.1.

String indexing in Python is zero-based: the first character in the string has index 0, the next has index 1, and so on. The index of the last character will be the length of the string minus one. For example, a schematic diagram of the indices of the string 'foobar' would look like this: String Indices.May 25, 2023 · The Python Modulo Operator. Basically, the Python modulo operation is used to get the remainder of a division. The modulo operator ( %) is considered an arithmetic operation, along with +, –, /, *, **, //.
