# ex1:快速排序算法
def quicksort(array):

    if len(array) <= 1:
        return array
    pivot = array.pop()
    less = [x for x in array if x <= pivot]
    greater = [x for x in array if x > pivot]
    return quicksort(less)+[pivot]+quicksort(greater)

array = [9, 8, 4, 5, 32, 64, 2, 1, 0, 10, 19, 27]
print(quicksort(array))

# ex2:交换两个变量,c语言需要用temp,python无需
a, b = 1, 2
b, a = a, b

# ex3:安全地操作文件
with open("./ex3.txt", 'r') as f:
    pass

# ex4:奇技淫巧,倒序输出
c = [1, 2, 3, 4]
print(c[::-1])
print(list(reversed(c)))

# ex5:字符串格式化
out_str = '{greet} from {language}.'.format(greet='Hello World', language='Python')
print(out_str)
### Python Code Examples for Expressing Love Certainly! Below are some creative and thoughtful ways to express love through Python code: #### Simple Heart Shape Using Print Statements A straightforward way to show affection is by printing a heart shape. ```python print(" *** ") print(" ***** *****") print(" *********** ") print("*** ***") print("* *") ``` This creates a visual representation of a heart using asterisks[^1]. #### Personalized Message Generator Creating personalized messages can add an extra layer of sentimentality. ```python def generate_love_message(name): message = f"Dear {name},\n\nYou mean the world to me." return message partner_name = "Alice" print(generate_love_message(partner_name)) ``` The function `generate_love_message` takes a name as input and returns a heartfelt message directed at that person[^2]. #### Interactive Love Calculator (for Fun) An interactive program where users can enter their names along with their partner's name to get a fun score indicating compatibility. ```python import random def calculate_love_score(your_name, partner_name): combined_names = your_name + partner_name score = sum(ord(char.lower()) - ord('a') + 1 for char in combined_names if char.isalpha()) final_score = score % 100 + 1 return min(final_score, 100) your_name = input("Enter your name: ").strip() partner_name = input("Enter your partner's name: ").strip() score = calculate_love_score(your_name, partner_name) print(f"\nThe love score between you and {partner_name} is {score}%!") if score >= 85: print("That’s incredibly high! True love might be found here.") elif score >= 60: print("It looks promising!") else: print("Keep nurturing this relationship; it has potential.") ``` In this script, user inputs two names which then go into calculating a pseudo-love percentage based on character values from ASCII codes. The result provides playful feedback about the likelihood of true love existing between those named individuals[^3]. --related questions-- 1. How do I modify these scripts to include more personal details? 2. Can such programs help improve communication within relationships? 3. What other types of symbolic patterns could one create using Python print statements besides hearts? 4. Is there any library specifically designed for generating romantic content via programming languages like Python?
