Python 编写几个经典例子：斐波那契数列，九九乘法表

#九九乘法表：

for i in range(1, 10):

        for j in range(1, i+1):

            print("%d%d=%d\t" % (j, i, ij), end="")

        print()

num=int(input("需要几项？"))

n1=0

n2=1

count=2

if num<=0:

    print("请输入一个整数。")

elif num==1:

    print("斐波那契数列:")

    print(n1)

elif num==2:

    print("斐波那契数列:")

    print(n1,",",n2)

else:

    print("斐波那契数列:")

    print(n1,",",n2,end=" , ")

    while count<num:

        sum=n1+n2

        print(sum,end=" , ")

        n1=n2

        n2=sum

        count+=1

print()

num = int(input("请输入一个数字: "))

sum = 0

n = len(str(num))

temp = num

while temp > 0:

    digit = temp % 10

    sum += digit * n

    temp //= 10

if num == sum:

    print(num, "是阿姆斯特朗数")

else:

    print(num, "不是阿姆斯特朗数")
