Welcome to the "Iteration & Flow" unit of the Python Academy! In this notebook, you will learn:

• Flow Control
• Indentation
• if-elif-else statements
• Loops: while and for
• continue and break
• List Comprehension

Building a program is essentially defining actions to perform depending on certain conditions. This can be setting up an alarm to trigger at midnight (time >> alarm), a weather forecast app (metereological conditions >> forecast) or discovering business insights from the latest financial reports (financial values >> analysis). Flow Control is what allows you to check for conditions, act accordingly and iterate on repeatable code.

In Python, the main concepts for flow control comprise:

• if a condition do something, or something else

• while a certain condition is true, continue iterating until it no longer applies
• for a specific number of times, repeat the same action
• manually controlling to continue to the next iteration of a loop, or else break the loop immediately.

List/dict/set comprehension is one of the things you want to be comfortable with if you want to write decent Python code. In here we present a short introductory video
