Python Tutorials for Absolute Beginners: Comments, Escape Sequences, and Print Statements

Comments

In Python, comments are employed whereby one is able to write remarks on existing code to enhance its understanding by others. Overview Figure 4 below is a diagrammatic representation of Python showing that they are not recognized by the Python interpreter. There are two types of comments: These include the single-line and multi-line formats of the two scripts.

Single-line Comments

A line comment uses the hash character (#) at the start of the whole line, and goes to the line end.

Multi-line Comments

Actually, double quotes can make multi-line comments: ''' or """ These are mainly used in docstrings that can comment on the effectiveness of a certain function or even a module.

Escape Sequences

Escape sequences are used as special markers to portray special characters within strings. They start with a backslash which is represented as “\”. Here are some common escape sequences:Here are some common escape sequences:

\n: Newline

\t: Horizontal tab

\\: Backslash

\': Single quote

\": Double quote

Print Statement

The print statement is used to display output to the console. You can print text (strings), numbers, variables, and even the results of expressions.

Basic Usage

Printing Variables

Using F-Strings (Formatted String Literals)

F-strings provide a way to embed expressions inside string literals, using curly braces {}. They are prefixed with the letter f.

Concatenation

You can concatenate strings using the + operator.

Printing with Separators and End Characters

You can use the sep and end parameters to modify the default behavior of the print function.

Example Program

Here's a small example program that combines these concepts:

This covers the basics of comments, escape sequences, and the print statement in Python. These are fundamental skills that will help you write clear and effective Python code.
