10个解决日常编程问题的 Python 代码片段_python优秀的代码片段-优快云博客

人生苦短，快学Python！

使用这些有用的 Python 代码片段提升你的编程技能，在本文中，我将分享 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，但其他片段对你来说，有可能是新的。我们现在开始吧。

1. 简单的 HTTP Web 服务器

# Simple HTTP SERVER
import socketserver
import http.server
PORT = 8000
handler = http.server.SimpleHTTPRequestHandler
with socketserver.TCPServer(("", PORT), handler) as http:
    print("Server Launch at Localhost: " + str(PORT))
    http.serve_forever()
# Type in http://127.0.0.1:8000/ in your webbrowser

2.单行循环List

# One Liner Loop throught 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]

3.更新字典

# Update Dictionary
mydict = {1: "Python", 2: "JavaScript", 3: "Csharp"}
mydict.update({4: "Dart"})
print(mydict) # {1: 'Python', 2: 'JavaScript', 3: 'Csharp', 4: 'Dart'}

4.拆分多行字符串

# Split Multi Lines String
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']

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}

6. 不使用 Pandas 读取 CSV 文件

# Simple Class Creation
import csv
with open("Test.csv", "r") as file:
    read = csv.reader(f)
    for r in read:
        print(row)
# Output
# ['Sr', 'Name', 'Profession']
# ['1', 'Haider Imtiaz', 'Back End Developer']
# ['2', 'Tadashi Wong', 'Software Engineer']

7. 将列表压缩成一个字符串

# Squash list of String
mylist = ["I learn", "Python", "JavaScript", "Dart"]
string = " ".join(mylist)
print(string) # I learn Python JavaScript Dart

8. 获取任何数据的类型

# Get Type of Any Data
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'>

9.修改打印功能

# 修改打印功能
print("Top Programming Languages are %r, %r and %r" % ('Py', 'Js', 'C#'))
# Output
# Top Programming Languages are 'Py', 'Js' and 'C#'

10. 获取数据占用的内存

# Get Memory taken by data
import sys
def memory(data):
    return sys.getsizeof(data)
print(memory(100)) # 28
print(memory("Pythonnnnnnn")) # 61

以上就是我今天跟你分享的10个Python的代码片段，希望你能发现这些 Python 代码片段它们的有用之处，并且用起来很有趣，然后，随时与你的程序员朋友分享这篇文章。
