by Defeng Kong (2014301020081)

1.Abstract

I'll make my name move from left to right and from up to down in the sceern by the main commends'os.system('cls')'and'time.sleep(t)' of python.Of course,the loop statement'while' is also needed.

2.Backgroud

Last week, I draw my name by using python.This week,I'll make it move in the screen by using python too.

3.The Main Body

1. from left to right
   the code:

import os
import time
i=1  
n1='********'
n2='   **'
n3='   **                           *****'
n4='   **         ***** *         *       *'
n5='   **       *       *         *       *'
n6='   **      *        *         *       *'
n7='   **      *        *         *       *'
n8='   **       *       *         *       *'
n9='********     ******  **       *        **' 
a=' '            
while(i<50):
     print n1
     print n2
     print n3
     print n4
     print n5
     print n6 
     print n7
     print n8
     print n9
     n1=a+n1 
     n2=a+n2 
     n3=a+n3 
     n4=a+n4 
     n5=a+n5
     n6=a+n6
     n7=a+n7
     n8=a+n8
     n9=a+n9
     i+=1
     time.sleep(0.5)
     os.system('cls')

2. from up to down
the code

import os
import time
i=1 
n='''
     ********
        **
        **                           *****
        **         ***** *         *       *
        **       *       *         *       *
        **      *        *         *       *
        **      *        *         *       *
        **       *       *         *       *
     ********     ******  **       *        **
                                              '''
a='''
   '''
while(i<50):
    print(n)
    n=a+n
    i+=1
    time.sleep(0.5)
    os.system('cls')

run:
GIF of name

4.Conclusion

For the item from left to right,I can also use the way of making the
strings to the list.in this way,I can add the " "to the front of every elements of list more simplier.
For The second question,I can't make it by myself.

5.Thanks
