: Appears at the end of a function definition statement

such as: if expression:

Elif expression:

else: etc

Defining functions Using Def

def Hanshu (x)

Description

Return (the value returned when the function is called)

The usage of default parameters is not very clear:

def foo (debug=true):
' Detemine if in debug mode with default argument '
If debug:
print ' in debug mode '
print ' Done '

The output is ' done ' when the value is False

If the true value only wants to output the first sentence, I think I should add continue to jump out of the loop,

But in reality, I've added continue to the error.

Class calls internal properties
First, define a class, and the properties and methods inside the class, such as:

If the base class must be defined as object, define ABC error

Class Hello (object):

a=0.5

The function is defined earlier

def add (x)

Return (X+X)

function call class with parameter

Add (HELLO.A)

Output is 1
