The flowchart of a for is like it follows:

This is the basic structure:

val is a certain value or ‘conditional’

Here is one example

Important information about for´s:

  • The for statement in Python has the ability to iterate over the items of any sequence, such as a list or a string.
  • If a sequence contains an expression list, it is evaluated first. Then, the first item in the sequence is assigned to the iterating variable iterating_var. Next, the statements block is executed. Each item in the list is assigned to iterating_var, and the statement(s) block is executed until the entire sequence is exhausted.

If statement:

The If statement is a conditional statement and works like this. If a value is true then the instruction stop and the code continues, but if the value is false, the code read the next line on the IF.

The syntaxis is like this:

if expression:
<body>
else:
<body>

Here is an example:
