在本文中，将分享10 个 Python代码片段，以帮助你应对日常编程挑战。你可能已经知道其中一些片段，但有些其他片段对你来说可能是新的。赶紧使用这些有用的 Python 代码片段提升你的编程技能吧。

1. 简单的 HTTP Web 服务器

# 简单的 HTTP 服务器 import socketserver import http.serverPORT = 8000 handler = http.server.SimpleHTTPRequestHandler with socketserver.TCPServer(("", PORT), handler) as http: print("Server Launch at Localhost: " + str(PORT)) http.serve_forever()#在浏览器中输入http://127.0.0.1:8000/ 123456

2.单行循环List

mylist = [10, 11, 12, 13, 14] print([i * 2 for i in mylist]) # [20, 22, 24, 26, 28] print([i * 5 for i in mylist]) # [50, 55, 60, 65, 70] 123'

3.更新字典

# 更新字典 mydict = {1: "Python", 2: "JavaScript", 3: "Csharp"} mydict.update({4: "Dart"}) print(mydict) # {1: 'Python', 2: 'JavaScript', 3: 'Csharp', 4: 'Dart'} 1234'

4.拆分多行字符串

# 拆分多行字符串 string = "Data \n is encrpted \n by Python" print(string) # Output # Data # is encrpted # by Python splited = string.split("\n") print(splited) # ['Data ', ' is encrpted ', ' by Python'] 123456789'

5. 跟踪列表中元素的频率

# Track Frequency import collections def Track_Frequency(List): return dict(collections.Counter(List)) print(Track_Frequency([10, 10, 12, 12, 10, 13, 13, 14])) # Output # {10: 3, 12: 2, 13: 2, 14: 1} 1234567'

6. 不使用 Pandas 读取 CSV 文件

# 简单的类创建 import csv with open("Test.csv", "r") as file: read = csv.reader(f) for r in read: print(row) # 输出 # ['Sr', 'Name', 'Profession'] # ['1', '小猴子', '数据挖掘工程师'] # ['2', '云朵君', '算法工程师'] 12345678910

7. 将列表压缩成一个字符串

# 压缩字符串列表 mylist = ["I learn", "Python", "JavaScript", "Dart"] string = " ".join(mylist) print(string) # I learn Python JavaScript Dart 1234'

8. 获取列表中元素的索引

# 获取列表中元素的索引 mylist = [10, 11, 12, 13, 14] print(mylist.index(10)) # 0 print(mylist.index(12)) # 2 print(mylist.index(14)) # 4 12345'

9. *arg 的魔法

# *arg 的魔法 def func(*arg): num = 0 for x in arg: num = num + x print(num) # 600 func(100, 200, 300) 1234567

10. 获取任何数据的类型

# 获取任意数据的类型 data1 = 123 data2 = "Py" data3 = 123.443 data4 = True data5 = [1, 2] print(type(data1)) # <class 'int'> print(type(data2)) # <class 'str'> print(type(data3)) # <class 'float'> print(type(data4)) # <class 'bool'> print(type(data5)) # <class 'list'> 123456789101112'
