Abstruct

1. Design a programe to make my Eglish name moved on the screen.

   Tips:

   • We can use this code to clean the screen.

   import os
   i = os.system('cls')

   • Words can be moved by adding space before each line.

   print("      ###")
   print("     #   ")
   print("     #   ")
   print("     #   ")
   print("      ###")

2. Draw something you want (such as rocket, matchstick man) in a 80×80 bitmap and make it rotate.

   Tips:

3. Make strings into lists.

   
a = "test"
l = list(a)


4. Make lists into strings.

   a = "".join(l)

1.L1

I use a loop statement to make it work. It will add some space in each loop and then clean the screen.
[Code][1]

import os
import time
i=os.system('cls')
a0 = "##### ##### #       # ##### #     #    # ######  #     # ######"
a1 = "   #  #     ##     ## #     #      #  #  #    #  # #   # #     "
a2 = "  #   ##### # #   # # ##### #        #   ######  #  #  # #  ###"
a3 = " #    #     #  # #  # #     #        #   #    #  #   # # #    #"
a4 = "##### ##### #   #   # ##### #####    #   #    #  #     # ######"
b = 0
while b < 11:
      print ('   '*b+a0)
      print ('   '*b+a1) 
      print ('   '*b+a2)
      print ('   '*b+a3)
      print ('   '*b+a4)
      time.sleep(1)
      i=os.system('cls')
      b += 1

Result
disadvantage: It can't move on the screen forever

Code

  import time
import os
a=("   ############\n")
b=("   ###      ###\n")
c=("       ####    \n")
d=("##################\n")
e=("        ##        \n")
f=("#####   ##  ######\n")
k=("    #########   ##\n")
g=3*a+6*b+2*c+2*d+2*c+2*a+4*b
h=3*e+3*f+4*k+3*f+3*e
i=4*b+2*a+2*c+2*d+2*c+6*b+3*a
j=3*e+3*f+4*k+3*f+3*e
li=[g,h,i,j]
i=0
while i<20:
    print(li[i%4])
    time.sleep(1)
    i=i+1
    os.system('cls')

Result
