Python—end=Usage

The code of the nine-nine multiplication table:

i=1
while i<=9:
    j=1
    while j<=i:
	    print(j,'*',i,'=',j*i,end='  ')  #打印完不换行，以两个空格结尾
	    j+=1
    print()                                  #换行
    i+=1

Printed result: 

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    

end= refers to the ending, not a newline. end=''can also be replaced with other ending methods, such as:

i=1
while i<=9:
    j=1
    while j<=i:
	    print(j,'*',i,'=',j*i,end=' / ')  #打印完不换行，以 / 结尾
	    j+=1
    print()                                  #换行
    i+=1

 Print result:

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 / 

In addition, print() is to print empty and then wrap by default.
