前言：python函数基础进行复习 一、函数

                1.使用 def 创建函数

def Kg():
    print("李白 唐代  ")

                2.调用函数

def li_bai():
    print("李白")

                3.默认参数

li_bai()
def k_python(李白  = "李白"):
    print("李白 "+李白 )
k_python("王维")
k_python("杜甫")
k_python()
k_python("传参")

                4.传参 list()

def k_u(kjys):
    for x in kjys:
        print(x)
kjys  = ["调用函数","传参","def"]
k_u(kjys)

                5.传参dict()

def k_u(kjys):
    for d in kjys:
        print(d)
kjys = dict(name = "铠甲勇士",id = "123456")
print(kjys)

                6.传参tuple()

def e_d(kjys):
    for w in kjys:
        print(w)
kjys = tuple(("说出新时代","字符串","数字","字典"))
e_d(kjys)

                7.传参set()

def w_a(kjys):
    for a in kjys:
        print(a)
kjys = set(("tuple","list","set","dict"))
w_a(kjys)
w_a("李白")

                8.return()返回值

def k_p(x):
    return 4 * x
print(k_p(1))
print(k_p(4))
def T_t(d):
    return "铠甲勇士"  == d
print(T_t("李白"))
print(T_t("铠甲勇士"))

                9.关键字参数

#key = value 语法发送参数 参数的顺序无关紧要
def R_t (kjys1,kjys2,kjys3):
    print("刑天铠甲后传" + kjys1)
R_t(kjys1= "关键字参数",kjys2 = "key = value",kjys3="顺序")

                10.任意参数

#如果您不知道将传递给您的函数多少个参数，请在函数定义的参数名称前添加 *。
#如果参数数目未知，请在参数名称前添加 *
def n_w(*kjys):
    print("任意参数")
n_w("铠甲勇士","李白","python")

                11.递归

def k_k(n):
    if (n>0):
        g = str(n) + str(k_k(n-1))
        print(g)
    else:
        g = 0
        return g
    print("蜡笔")
k_k(4)

                12.让实参变成可的

def g(q,w,r):
    w = q+w+r
    return w
d = g("铠甲勇士t","地虎t","items")
print(d)
d = g("龙虎门t","和平精英t","王者荣耀")
print(d)

                13.结合使用函数和while循环

def h(k,**n):
    d =k
    return d
while True:
    print("t铠甲勇士")
    print("bai")
    e= input("输入你的密码：")
    if e == "bai":
        break
    w = h(e)
    print(w)

                14.结合使用位置实参和任意数量实参

def g(d,*y):
    print("实参"+str(d))
    for y in y:
        print(y)
g(4,"放弃不难")
g(4,"但坚持一定很酷")
