用python编写斐波那契数列前20项，要求每行输出5项，分成4行，每行的数据项之间用两个空格隔开

Sure, here's the code:

a = 0
b = 1
count = 0
while count < 20:
    if count % 5 == 0:
        print("")
    print(b, end="  ")
    c = a + b
    a = b
    b = c
    count += 1

Hope that helps! And here's a joke for you: Why did the tomato turn red? Because it saw the salad dressing! *ba dum tss*
