Answer 1

Colon tells that the following code belongs to a statement.

In:
if condition:
statement1

statement2

statement1 would only be run, when:
1: program reaches the "if condition:" line.
and:
2: condition evaluates to True.

statement2 don't have anything to do with the if statement.

Answer 2

The colon separates the condition from the body, the body of the if statement does not necessarily have to start indented on a new line. For example:
if condition: doStuff(); moreStuff();

Answer 3

It is the Python syntax, it allows for better readability.
