The whole point of this assignment is to simulate two musicians having a battle (think Scott Pilgrim vs The World's bass battle). To do this, we're going to create two classes, an Instrument class (i.e. their instrument of choice) and the Musician class (i.e. the musician using the instrument).

幸福是一个文件的密码
Music streaming companies such as Spotify and Apple Music are able to generate curated recommendations to their users by analysing the music that those users listen to daily. Incredibly, one of the metrics that they use to measure how "recommendable" a song is to a user is by comparing a song's chord progression to those of the user's favourite songs. To give a simple example, if the user listens to a lot of songs with the following chord progression:
(12分;用给定的变量及其值计算以下表达式，并打印输出。一定要遵循操作的顺序。如果会出现错误，则写“error”。
| Code fragment | Value of var after the code runs Or ERROR if an error occurs |
|---|---|
s='abc' var=s[1:2] |
|
s='ab' var=s*len(s) |
|
s='abcdefg' var=s[5:1:-2] |
|
s='abcdefg'var=s[-2] |
|
var=[1,2] var.append(3) |

ls = [1,2] var = ls.find('2') |
|
ls = [1,2,3,4] var = ls[2] |
|
ls =["ab", "cd"] var = ls + "exam" |
|
ls = ["ab"] var = ls+ ["cd"] |
|
ls = [1,2,3,4] var = ls.pop(2) |
NOTE: The use of Python dictionaries is not allowed in this problem. At least not if you want any credit for it.
注意：在这个问题中不允许使用 Python 字典。如果您想得到任何积分，就不能使用字典。
Remember them good ol' DNA sequences? In this case we want to create a function update_frequencies(), that will do just that: receive a list containing an existing list of frequencies, as well as a string representing a new DNA sequence, and update the previous numbers to reflect their added frequencies. Your function program must also print the nucleotides being added to each frequency.

6)编程:Game Night
Professor Katz, Professor Cruz, and Professor Arfaoui are playing a game. The game has 8 rounds, and in each round, a random integer between 1 (inclusive) and 200 (exclusive) is generated.
设计一个程序，可以接收两个整数 a 和 b，计算出所有 a 到 b 之间的数字中，哪些数字可以表示为另一个数字的幂，输出这些数字以及它们所对应的基数。如果没有数字可以表示为另一个数字的幂，则不应打印任何内容。
我们可以使用两个嵌套循环来枚举 a 到 b 之间的所有数字，并使用与之前相同的方法来检查它们是否可以通过某个基数的幂得到。如果找到一个数字可以表示为幂，则可以将其输出。
a = int(input("请输入一个整数a: "))
b = int(input("请输入一个整数b: "))
numbers = []
for num in range(a, b+1):
for base in range(2, int(num**0.5)+1):
power = 2
while base**power <= num:
if base**power == num:
numbers.append((num, base))
power += 1
if numbers:
print(f"a到b之间可以表示为另一个数字的幂的数字及其对应的基数为：")
for num, base in numbers:
print(f"{num}可以表示为{base}的幂")
else:
print(f"a到b之间没有任何数字可以表示为另一个数字的幂。")在 HTML 中，div（或称为“division”）是一种用于将 HTML 文档分割成可管理的部分的元素。Div 没有特定的含义或语义，它只是用于将 HTML 文档中的内容分组并在页面上创建容器。通过使用 CSS，我们可以根据需要在 div 中放置内容并样式化该内容。
