Basic Concepts of Python for Beginners
Here are some basic concepts in Python for beginners –
A variable is a container for storing a value in Python. By assigning a value to a variable with the "=" operator, you can create a variable. Any data type, including strings, integers, and floating-point numbers, can be used to represent the value. A variable can be used throughout your program once it has a value.
Data Types Strings, integers, and floating-point numbers are just a few of the built-in data types available in Python. In Python, the type of value a variable holds is referred to as a data type.
There are a few pre-built data types in Python:
Numbers: This includes floating-point numbers like 3.14 and 1.23, as well as integers like 1, 2, and 3. A sequence of characters, such as "hello" and "world," is called a string. Single or double quotes can be used to enclose strings. Lists: A collection of items that can be arranged in any order. Items are separated by commas in lists, and square brackets are used to write them. Tuples: Similar to a list, a tuple cannot be changed because its items cannot be changed. Round brackets are used to write plurals, and commas are used to separate items. Dictionary: Key-value pairs are the foundation of a dictionary.
Curly braces are used to write dictionaries, and colons are used to separate values and keys in Boolean: True or False, there is no such thing as a Boolean data type: The null value or none is represented by the special constant None. The built-in type() function can be used to determine a variable's data type.
Operators Python provides support for a variety of logical and mathematical operators, including +, -, *, /, and %. Operators are special symbols in Python that carry out particular operations on one or more operands (the values or variables being operated on).
It is used to execute various codes based on particular conditions with conditional statements. The if-else statement is the most prevalent type of conditional statement. The following is the basic syntax for an if-else statement:
