Python：函数篇(每周练习)

编程题：

Python第四章作业（初级） (educoder.net)

题一：无参无返回值函数

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

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

题三：有参有返回值函数

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

def say_hi_gender(full_name, gender):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')
say_hi_multi_parameter('杜甫', '李白', '柳宗元', '李商隐')

题六：pow函数详解

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

题七：fabs() 函数

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

def sefDivisor(n):if '0' in str(n):return Falsefor i in str(n):if n % int(i) != 0:return Falseelse:return Truen = 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

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