Block

A block of code is a set of statements, functions or instructions that are grouped together. In most programming languages the blocks of code are created by using curly braces ({}). For instance, in C the statements executed when a test condition is met would be written as:

if (testCondition) {
   statement1;
   statement2;
   statement3;
}

In Python a block of code is created by using indentation.

• In the if and for the code starts with a colon (:)
• The next line after the colon should be indented
• The block ends when the indentation goes back to the previous level.

The standard is to create the indentation by using four spaces.
