python实现for和while九九乘法表

#九九乘法表For实现

for i in range(1,10):
    for j in range(1,i+1):
        sum = i * j
        print("%dx%d=%d"%(j,i,sum),end="\t")
    print() #换行

 

#九九乘法表while实现

i = 1
while i<=9:
    j = 1
    while j<=i:
        print("%dx%d=%d"%(j,i,i*j),end="\t")
        j += 1
    print()
    i += 1
