Python的几个编程作业..求教TAT刚开始学....
作业要自己做

Print = input("请输入需要强调的话：")
Print = Print + "!"
number = int(input("请输入要重复的次数："))
print(Print * number)
Python作业题目
你好的！
我给你做一下第17 题：别的问题需要答案的话，挨个提问，否则没人一下给你回答那么多的问题
import math
def is_prime(n): # 简化问题，先利用函数判断是否为质数
if n == 1: # =是赋值，==才是判断，切记切记
return False
for i in range(2, int(math.sqrt(n))+1): # 质数判断条件，注意+1
if n % i == 0:
return False
return True
primes = []
name = int(input())
if is_prime(i) is True: # bool值用is判断
print('the input number is prime number;')
else:
print('the input number is not a prime number;')
学计算机的同学帮看一个python入门的作业？
编写程序，从键盘上输入三个数字，用输入的第一个数字除以第二个数字，得到的结果和第三个数字相加，在这个过程中注意要捕获异常，根据错误类型去进行异常处理，如果没有触发异常的话，要输出最后的计算结果，程序的最后要输出提示语:程序执行结束。
