Python九九乘法表的四种输入方法

第一种（while、while）：

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

第二种（for、for）:

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

第三种（while、for）:

i=1
while i<=9:
    for j in range(1,i+1):
        print(j,"*",i,"=",j*i,end="\t")
    print()
    i+=1

第四种（for、while）:

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