I. Print the 9-9 multiplication table in a for Loop

1.1 lower left corner

　　for i in range(1,10): 　　　　for j in range(1,i+1):　　　　　　　　print('%d*%d=%2d\t'%(j,i,i*j),end='')　　　　print()

:

1.2 bottom right corner

For I in range (): for k in range (I +): print (end = '') # Eight spaces are returned, note that for j in range (1, I + 1): print ('% d * % d = % 2d \ t' % (j, I, I * j ), end = '') print ()

1.3 upper left corner

For I in range (9, 0,-1): for j in range (1, I + 1 ): print ('% d * % d = % 2d \ t' % (j, I, I * j), end = '') print () # The main purpose here is to use the print feature for line feed.

1.4 upper right corner

For I in range (): for k in range (1, I): print (end = '') # Eight spaces for j in range (9, I-1, -1): print ('% d * % d = % 2d \ t' % (I, j, I * j), end = '') print ()

Ii. while loop print multiplication table (four methods)

2.1 lower left corner

　　i = 1　　while i <=9:　　　　j = 1　　　 while j <= i:　　　　　　print('%d*%d=%2d\t'%(i,j,i*j),end='')　　　　　　j+=1   print()   i +=1

:

2.2 bottom right corner

I = 1 while I <= 9: k = 9 while k> I: print (end = '') # Eight spaces k-= 1 j = 1 while j <= I: print ('% d * % d = % 2d \ t' % (j, I, I * j), end = '') j + = 1 print () I + = 1

2.3 upper left corner

　　i = 9　　while i >= 1:　　　　j = 1　　　　while j <= i:　　　　　　print('%d*%d=%2d\t'%(j,i,i*j),end='')　　　　　　j +=1　　　　i -= 1　　　　print()

2.4 upper right corner

I = 9 while I> = 1: k = 9 while k> I: print (end = '') # Eight spaces k-= 1 j = 1 while j <= I: print ('% d * % d = % 2d \ t' % (j, I, I * j), end = '') j + = 1 print () I-= 1

The above example of printing the 9-9 multiplication table using the Python loop (including while & for) is all the content shared by the editor. I hope to give you a reference, we also hope that you can support the customer's home.
