Sequencing<\/h3>\n

Sequencing refers to the order in which statements are executed. Code is typically executed in a sequential manner, line by line, from top to bottom. Each statement is executed after the previous statement has finished.<\/p>\n

Sequencing in Python<\/strong><\/p>\n

Sequencing in Python is achieved by executing code on line at a time, from the top to the bottom.<\/p>\n

Sequencing in flowcharts is indicated using arrows, flowing from one command to the next.<\/p>\n

Selection<\/h2>\n
\n\n
Selection<\/h3>\n
Selection, also known as conditional execution, allows you to choose different paths of execution based on a condition. It involves using conditional statements (such as if<\/code>, else if<\/code>\/elif<\/code>, and else<\/code>) to determine which code block should be executed.<\/p>\n

In Python selection can be achieved through:<\/p>\n
