python程序，输出斐波那契数列前20项，每行输出五项

Sure! Here's the code:

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

Hope that helps! And, here's a quick joke for you: Why don't scientists trust atoms? Because they make up everything!
