【python的for循环嵌套打印如下图形】

图形一：

输出结果：

******* ******* ******* *******

Python3.6代码：

for i in range(0,4): for j in range(0,7): print("*",end="") print()

图形二：

输出结果：

* *** ***** *******

Python3.6代码：

for i in range(1,8,2): for j in range(i): print("*",end="") print()

图形三：

输出结果：

* *** ***** ******* ***** *** *

Python3.6代码：

for i in range(1,8,2): for j in range(i): print("*",end="") print() for i in range(5,0,-2): for j in range(i): print("*",end="") print()

图形四：

输出结果：

* *** ***** *******

Python3.6代码：

for i in range(1,8,2): print(int((7-i)/2)*" ",end="") for j in range(i): print("*",end="") print()

或者：

for i in range(1,8,2): for j in range(int((7-i)/2)): print(" ",end="") for j in range(i): print("*",end="") print()

图形五：

输出结果：

* *** ***** ******* ***** *** *

Python3.6代码：

for i in range(1,8,2): print(int((7-i)/2)*" ",end="") for j in range(i): print("*",end="") print() for i in range(5,0,-2): print(int((7-i)/2)*" ",end="") for j in range(i): print("*",end="") print()

或者：

for i in range(1,8,2): for j in range(int((7-i)/2)): print(" ",end="") for j in range(i): print("*",end="") print() for i in range(5,0,-2): for j in range(int((7-i)/2)): print(" ",end="") for j in range(i): print("*",end="") print()

【python的for循环嵌套打印如下九九乘法表】

输出结果：

1 * 1 = 1 2 * 1 = 2 2 * 2 = 4 3 * 1 = 3 3 * 2 = 6 3 * 3 = 9 4 * 1 = 4 4 * 2 = 8 4 * 3 = 12 4 * 4 = 16 5 * 1 = 5 5 * 2 = 10 5 * 3 = 15 5 * 4 = 20 5 * 5 = 25 6 * 1 = 6 6 * 2 = 12 6 * 3 = 18 6 * 4 = 24 6 * 5 = 30 6 * 6 = 36 7 * 1 = 7 7 * 2 = 14 7 * 3 = 21 7 * 4 = 28 7 * 5 = 35 7 * 6 = 42 7 * 7 = 49 8 * 1 = 8 8 * 2 = 16 8 * 3 = 24 8 * 4 = 32 8 * 5 = 40 8 * 6 = 48 8 * 7 = 56 8 * 8 = 64 9 * 1 = 9 9 * 2 = 18 9 * 3 = 27 9 * 4 = 36 9 * 5 = 45 9 * 6 = 54 9 * 7 = 63 9 * 8 = 72 9 * 9 = 81

Python3.6代码：

for i in range(1,10): for j in range(1,i+1): print(i,"*",j,"=",i * j,end=" ") print()

图形X：

代码：

for line in range(0,3): for star in range(line): print(".",end="") print("O",end="") for star in range(5-2*line): print(".",end="") print("O",end="") for star in range(line): print(".",end="") print() for line in range(1,2): for star in range(3): print(".",end="") print("O",end="") for star in range(3): print(".",end="") print() for line in range(2,-1,-1): for star in range(line): print(".",end="") print("O",end="") for star in range(5-2*line): print(".",end="") print("O",end="") for star in range(line): print(".",end="") print()

如果代码可以改进，有劳指出，非常感谢~
