知识点：if...elif...else...

a = int(input())
for i in range(1,a+1):
    if i % 2 == 0 and i % 3 == 0:
        print("HelloWorld")
    elif i % 2 == 0:
        print("Hello")
    elif i % 3 == 0:
        print("World")
    else:
        print(i)

写成函数，调用函数

def helloworld(a):
    for i in range(1,a+1):
        if i % 2 == 0 and i % 3 == 0:
            print("HelloWorld")
        elif i % 2 == 0:
            print("Hello")
        elif i % 3 == 0:
            print("World")
        else:
            print(i)
a = int(input())
helloworld(a)
