# 默认参数
def repeat_str(s,times =2):repeated_strs =s*timesreturn repeated_strsrepeated_string = repeat_str("happy birthday! ")
print(repeated_string)
# 覆盖默认参数
repeated_string = repeat_str("happy birthday! ",4)
print(repeated_string)
repeated_string = repeat_str("happy birthday! ",)
print(repeated_string)#def fuc(a,b=4,c=8):print("a is ",a,"and b is ",b,"and c is ",c)fuc(13,17)
# 跳过b赋值
fuc(125,c = 24)
fuc(c=23,a=1)
# 有点类似与参数的指针，*对应的list，**对应字典
def print_paras(fpara, *nums, **words):print("fpara: "+str(fpara))print("nums "+str(nums))print("words： "+str(words))print_paras("hello",1,3,5,7,word ="python",anathor_word ="java")
