python日常小基础集锦

1、pymysql模块的简单使用

import pymysql

db = pymysql.connect("localhost", "root", "123456", "test")

cursor = db.cursor()

cursor.execute("select version()")

data = cursor.fetchone()

print(data)

cursor.execute("insert into t1 values(1, 'ling')")

db.commit()

db.close()

 

2、random的使用

import random

data = random.randint(0,100)

print(data)

 

3、range的使用

for i in range(0,100):

  print(i)
