备忘单Python是一个用于Python程序员的实用工具,提供了Python编写中最常用的代码片段和方法。
备忘单Python可以通过pip安装:
pip install memorandum-python
导入备忘单Python:
import memorandum
备忘单Python的代码片段可分为以下几类:
string1 = 'Hello'
string2 = 'World'
string3 = string1 + ' ' + string2
print(string3) # 输出:'Hello World'
string = 'Hello World'
new_string = string.replace('World', 'Python')
print(new_string) # 输出:'Hello Python'
string = 'Hello World'
sub_string = string[0:5]
print(sub_string) # 输出:'Hello'
list = [1, 2, 3, 4, 5]
sub_list = list[0:3]
print(sub_list) # 输出:[1, 2, 3]
with open('file.txt', 'r') as file:
content = file.read()
print(content)
with open('file.txt', 'w') as file:
file.write('Hello World')
import requests
response = requests.get('http://www.example.com')
print(response.text)
import MySQLdb
db = MySQLdb.connect(
host='localhost',
user='root',
password='password',
database='example_db',
port=3306
)
cursor = db.cursor()
cursor.execute('SELECT * FROM example')
result = cursor.fetchall()
print(result)
