Python：打印矩形及九九乘法表

打印矩形

# while条件语句打印矩形
j = 0 
while j < 5: # 外层循环控制有几行j += 1i = 0while i < 5: # 内层循环控制列，即控制一行有几个*，i小于几这一行就有几个*i += 1print('*', end = ' ') # 打印* * * * * print()  # 换行# for循环打印矩形
j = 0
for j in range(0,10):j += 1i = 0for i in range(0,10):print('*', end=' ')print()

打印九九乘法表

# while条件语句打印九九乘法表
j = 0
while j < 9:j += 1i = 0while i < j: i += 1print(i,'*',j,'=',i*j, end = '\t',sep='')print()# for循环语句打印九九乘法表
for j in range (1,10):j += 1for i in range (0,j-1):i += 1print(i,'*',j-1,'=',i*(j-1), end='\t',sep='')print()
