1、打印九九乘法表

#只打印結果for i in range(1,10):  for j in range(1,i+1):    print(i*j,end=" ")  print() #打印算數表達式for i in range(1,10):  for j in range(1,i+1):    print("{0}*{1} = {2:2}".format(j,i,i*j),end=" ")    print() 1*1 = 1 1*2 = 2 2*2 = 4 1*3 = 3 2*3 = 6 3*3 = 9 1*4 = 4 2*4 = 8 3*4 = 12 4*4 = 16 1*5 = 5 2*5 = 10 3*5 = 15 4*5 = 20 5*5 = 25 1*6 = 6 2*6 = 12 3*6 = 18 4*6 = 24 5*6 = 30 6*6 = 36 1*7 = 7 2*7 = 14 3*7 = 21 4*7 = 28 5*7 = 35 6*7 = 42 7*7 = 49 1*8 = 8 2*8 = 16 3*8 = 24 4*8 = 32 5*8 = 40 6*8 = 48 7*8 = 56 8*8 = 64 1*9 = 9 2*9 = 18 3*9 = 27 4*9 = 36 5*9 = 45 6*9 = 54 7*9 = 63 8*9 = 72 9*9 = 81 #將打印矩陣轉置一下for i in range(1,10):  print(" " *10*(i-1), end = " ")  for j in range(i,10):    print("{0}*{1} = {2:<2}".format(i,j,i*j),end=" ")  print()    1*1 = 1  1*2 = 2  1*3 = 3  1*4 = 4  1*5 = 5  1*6 = 6  1*7 = 7  1*8 = 8  1*9 = 9       2*2 = 4  2*3 = 6  2*4 = 8  2*5 = 10 2*6 = 12 2*7 = 14 2*8 = 16 2*9 = 18            3*3 = 9  3*4 = 12 3*5 = 15 3*6 = 18 3*7 = 21 3*8 = 24 3*9 = 27                 4*4 = 16 4*5 = 20 4*6 = 24 4*7 = 28 4*8 = 32 4*9 = 36                      5*5 = 25 5*6 = 30 5*7 = 35 5*8 = 40 5*9 = 45                           6*6 = 36 6*7 = 42 6*8 = 48 6*9 = 54                                7*7 = 49 7*8 = 56 7*9 = 63                                     8*8 = 64 8*9 = 72                                          9*9 = 81 

2、打印一個菱形(行數為奇數行)

for i in range(-3,4):  prespace=(-i if i<0 else i)  print(" "*prespace + '*'*(7-2*prespace))   * *** ************ ***** ***  *   #變形之打印一道閃電while True:  line_max = int(input("please input a odd number: "))  if line_max % 2:    breakrange_num = (line_max + 1)//2 for i in range(-range_num+1,range_num):  if i == 0:    print('*'*line_max)  elif i > 0:    print(' '*(range_num-1) + "*"*(range_num-i))  else:    print(' '*(-i) + '*'*(range_num+i))   * ** **********  ***  **  * #變形之打印掏空的菱形for i in range(-4,5):  if i == -4 or i == 4:    print('*'*9)  else:    prespace=(-i+1 if i<0 else i+1)    print("*"*prespace + ' '*(9-2*prespace) + "*"*prespace) ************* *******  *****   ***    ***   *****  ******* *************

3、打印100以內的斐波那契數列

f0, f1 = 0, 1while f1 <= 100:  print(f1, end = " ")  t = f1  f1 = t + f0  f0 = t

暫時還不理解的寫法：

f0, f1 = 0, 1while f1 <= 100:  print(f1)  f0, f1 = f1, f0 + f1 #python對這樣的賦值怎樣處理

4、求斐波那契數列第101項

f0, f1 = 0, 1for i in range(3,102):  t = f1  f1 = t + f0  f0 = telse:  print(f1)
