The third day of learning pyton

Small knowledge function: Note that the above two functions involve calling

#function

 

 

1. First, you must learn to write code that Luo and see where is reusable

2. The code is then converted to the repeated use of a parameter, brought into the function

 

# Function body

 

DEF funcName ([param]): 
    executable 
    [retrue]

# Writing array

= G [ ' noodles ' , ' ham ' , ' beer ' ]

# Can do if you do not have too much trouble if

Learning the code: The main function is to call

# Simple lottery Code

def zr():

    a = input ( "Please enter a name")

    b = ['zr1']

    if a in b:

        print ( 'Congratulations')

    else:

        print ( 'I'm sorry, you pass and awards, but do not be discouraged')

zr()
