[Python study notes Day17] 4.1 python function of Lego

There are three parts python functions, objects, and modules may simplify the procedure

1. Create a function

   def myfunction():
def myfunction():
    print("this is my first function\nI am excited\nThank you!!!")

2. call function

1) function name ()

myfunction()

When a function call is looking forward function name, if part of the Wang Qianmian not find, you can not perform the
mechanisms function and circulation is actually similar principle, but adds a parameter

2) Parameters

def myfuc1(name):
    print(name + ' I love weivid')
myfuc1('nihao')

def add(num1,num2):
    result = num1 +num2
    print(result)
add(1,2)    #执行1+2 ，结果为3

3) return function return value

In return function using

def add(num1,num2):
    return(num1 + num2)

print(add(4,2))    #执行完4+2时，返回值作为print函数的参数，打印6
