BRANCHING IN PROGRAMMING
Sometimes you will want your program to "make a choice" based on a condition. To do one thing if the condition is True; do something else if its False. The IF-ELSE structure gives you that power.

IF-ELSE (ELIF) statements ate control statements used in python for decision making. The IF statement evaluates an expression and will execute the follow up "Block of Code" if only when the condition is True. If the condition resolves to a False Value, then the else statement is executed.

IF-ELSE (ELIF) relies heavily of Boolean values and Boolean operations

BLOCK OF CODE (INDENTATION IN PYTHON) - 23:10
Indentation is one of python most unique features also one of its most controversial features ("Spaces vs Tabs Debate").

By indenting the line it a block; A block is one or more consecutive lines indented by the same amount (of spaces); together they form a single unit/ "Block of Code:


INTRODUCTION TO LOOPS - 26:49
loops are control statement in programming for iterating over a statement(block of code) or a given sequence. It simply means to (go over/ repeat)

In python; we have two Loops: The FOR and WHILE loop

WHILE LOOP
In python, the while loop is used to execute a block of statement repeatedly until a given condition is met.
