Python函数的返回值

函数返回多个值时，结果为元组。

def fun(num):
    odd = [] # 存奇数
    even = [] # 存偶数
    for i in num:
        if i%2:
            odd.append(i)
        else:
            even.append(i)
    return odd, even
#函数的调用
lst = [10, 29, 34, 23, 44, 53, 55]
print(fun(lst))

def fun1():
    print('hello')
    #return
fun1()

def fun2():
    return 'hello'
res = fun2()
print(res)

def fun3():
    return 'hello', 'world'
print(fun3())
