def print_hi_human():  # 函数名用小写字母
    
        print("人类，你好！")
    
    if __name__ == '__main__':
        print_hi_human()

### 题二：无参有返回值函数 ###

        return "人类，你好！"
    
    if __name__ == '__main__':
        char = say_hi_human()
        print(char)

### 题三：有参有返回值函数 ###

![555102af11ad450b8b6ef789b1567ee9.png][]

def say_hi_person(full_name):  # 函数名用小写字母，函数名填空
        char = full_name + "，你好！"
        return char
    if __name__ == '__main__':
        #  函数名作为print()函数的参数，输出say_hi_human()的返回值。输入的人名作为函数的参数
        person_name = input()   
        char = say_hi_person(person_name)
        print(char)

### 题四：多参函数 ###

        if(gender == '男'):
            print('尊敬的{}先生，欢迎来到火星！'.format(name))
        elif(gender == '女'):
            print('尊敬的{}女士，欢迎来到火星！'.format(name))
        else:
            print('尊敬的{}先生/女士，欢迎来到火星！'.format(name))
        
    
    
    if __name__ == '__main__':
        name = str(input())
        gender = str(input())
        say_hi_gender(name, gender)

### 题五：任意数量参数 ###

def say_hi_multi_parameter(*name):    # 括号里填上参数
        for i in name:
            print('{}，你好！'.format(i))
    
    
    say_hi_multi_parameter('孟浩然')

### 题六：pow函数详解 ###

![a9ae31bc693a40f8af24030fd18e117f.png][]

x = float(input())
    y = float(input())
    num = pow(x,y)
    print(x**y)

### 题七：fabs() 函数 ###

![f770a3d8dc7649aea8c0e5bc146d8786.png][]

def fabs(x):
        """返回x的绝对值"""
        # 补充你的代码
        return abs(x)
    
    if __name__ == '__main__':
        n = float(input())
        print(fabs(n))

### 题八：汽车迷 ###

def Car(year,type1,a = "宝马"): # 括号里补充你的代码
        a = '这是一辆{:}年生产，型号是{:}的{:}牌汽车。'.format(year,type1,a)
        return a
    
    # 以下内容不要修改
    ls = input().split()  # 根据空格切分输入字符串为列表
    print(Car(*ls))       # 调用函数，取列表中的全部数据做参数

### 题九：编写函数输出自除数 ###

![95a80abba8a4428abb0260318152991a.png][]

def sefDivisor(n):
        if '0' in str(n):
            return False
        for i in str(n):
            if n % int(i) != 0:
                return False
        else:
            return True
    
    
    n = int(input())
    for m in range(1,n+1):
        if sefDivisor(m):
            print(m,end = ' ')

### 题十：二分法求平方根B ###

![bc6a88fe96aa407cb80389957d38099c.png][]

def sqrt_binary(x,g):
        low = 0
        high = x + 0.25
        m = (low + high) / 2
        while abs(m ** 2 - x) > g:
            if m ** 2 < x:
                low = m
            else:
                high = m
            m = (low + high) / 2
        print(f'{m:.8f}')
        print(f'{sqrt(x):.8f}')
    
    from math import sqrt
    x, g = input().split(',')
    sqrt_binary(float(x), float(g))
