1、创建1000张表

import pymysqldbhost = "10.1.1.143"
dbuser = "root"
dbpassword = "123456"
dbname = "demo_cg1000"
dbport = 3306
dbconn = pymysql.connect(host=dbhost, user=dbuser, password=dbpassword, db=dbname, port=dbport)mycursor = dbconn.cursor()for num in range(1, 1001):# print (num)tablename = "user" + str(num)sql = "CREATE TABLE  %s (col1 INT PRIMARY KEY     NOT NULL,col2    varchar(300)    DEFAULT NULL,col3    varchar(300)    DEFAULT NULL,col4    varchar(300)    DEFAULT NULL,col5    varchar(300)    DEFAULT NULL,col6    varchar(300)    DEFAULT NULL,col7    varchar(300)    DEFAULT NULL,col8    varchar(300)    DEFAULT NULL,col9    varchar(300)    DEFAULT NULL,col10    varchar(300)    DEFAULT NULL)" % tablenamemycursor.execute(sql)dbconn.close

2、创建1张有50个+字段的表

import pymysqldbhost = "10.1.1.143"
dbuser = "root"
dbpassword = "123456"
dbname = "demo_cg1000"
dbport = 3306
dbconn = pymysql.connect(host=dbhost, user=dbuser, password=dbpassword, db=dbname, port=dbport)mycursor = dbconn.cursor()fields = []
for i in range(1, 60):fields.append(f'a{i} VARCHAR(255)')create_table_sql = f'CREATE TABLE mytable11 ({", ".join(fields)});'
print(create_table_sql)
mycursor.execute(create_table_sql)dbconn.close
