Introduction

Usually,we think computer language is a boring thing.In order to figure out a thing,programmer will type too many lines of codes without any mistake.But today's problem is to make the static character move on the screen.It's a really funny thing to do!

Text

Use any means to make your English name or anything like it move.
The following is the code

import os
import time
def benpaobalanxiang():
    for i in range(150):
        print('wu fanfan\n')        
        print(' '*i+'                             ___')         
        print(' '*i+'                     /======/')
        print(' '*i+'            ____    //      \___       ,/')
        print(' '*i+'             | \\  //           :,   ./')
        print(' '*i+'     |_______|__|_//            ;:; /')
        print(' '*i+'     |_______|__|_//            ;:; /')
        print(' '*i+'    _L_____________\o           ;;;/')
        print(' '*i+'____(CCCCCCCCCCCCCC)____________-/_____________________')
        time.sleep( 0.2 )
        os.system("cls")
time.sleep( 10 )        
benpaobalanxiang()

we can make the printed praph move from left to right

Conclusion

We can let the figure move from left to right.Using the same way we can move anything like this.

Now we tend to the rotation of the figure(The effect is not well)

The code is the following
First,make a initial.txt

the next is the code

import os
import math
import time
def read_initial(initial_file):           ######## read the initial.txt and transfer it into a 2d list
    itxt= open(initial_file)
    initial_screen=[]
    for lines in itxt.readlines():
        lines=lines.replace("\n","").split(",")
        initial_screen.append(lines)
    itxt.close()
    for i in range(len(initial_screen)):
        initial_screen[i].extend(initial_screen[i][0])
        del initial_screen[i][0]
    return initial_screen
def rotation(angle,xscreen,l2,s,x_):
    if (angle != 0):
        for j in range(l2):
            if (xscreen[x_][j] == s):
                radius = j - 60
                x = int(radius*math.cos(angle*math.pi/180))+60
                y = int(radius*math.sin(angle*math.pi/180))+x_
                xscreen[y][x] = xscreen[x_][j]
                xscreen[x_][j] = ' '
            else:
                pass
        return xscreen
    else:
        return xscreen 
def output_screen(l,w,oscreen):
    final_screen = [' ']*(w-1)
    for i in range( w-1):
        for j in range(l-1):
            final_screen[i] = final_screen[i]+oscreen[i][j]
        print (final_screen[i])
    print ('\n') 
def main():
    while True:
        hours = time.localtime(time.time())[3]
        if (hours >=12):
            hours = hours - 12
        minutes = time.localtime(time.time())[4]
        seconds = time.localtime(time.time())[5]
        iscreen = read_initial('initial.txt')
        length = len(iscreen[0])
        width = len(iscreen)
        fscreen = rotation(((hours+minutes/60)*30)-90,rotation((minutes*6)-90,rotation((seconds*6)-90,iscreen,length,'^',23),length,'*',22),length,'$',21)
        output_screen(length,width,fscreen)
        time.sleep(0.5)
os.system('cls')
main()

the result is

Thank

Thank Caihao for his hint.
1、Use the "import os i=os.systerm('cls')" to clean the screen
2、add space before each line to make the character move
Thank Chengfen liu yutao for their reminder.
