This article brings you example code about using Python to create an employee information table. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

This is a comprehensive exercise question, the requirements are as follows:
Create an employee information table, the format is:

#字段1,字段2,字段3,字段4,字段5
#1,***  ,***  ,  *******,***
#2,***,  ***, *******,***
#3,*** ,***   ,  *****,  ***

Requirements can be queried based on conditional statements, the format is select where Separate commands with spaces

def emp(): 
    lis_res = [[],[],[],[],[]] #定义最终存储数据的列表
    with open('yuangong','r',encoding='utf-8') as f:
        cha = input('请输入查询语句，格式为：select *** where *** > ***').strip()
        lis = cha.split(' ')#定义存放输入语句的列表
        n = [] #n表示符合查询变量的字符串所在列表位置
        if lis[0] == 'select' and lis[2] == 'where':#设定关键字条件
            lis1 = lis[1].split(',')#定义查询元素的列表
            lis_title = f.readline().split(',') #文件中第一行为字段名
            lis_title = [s.strip() for s in lis_title]#列表推导式，去掉每个元素两边的空格
            for v in lis1:#循环遍历要查询的字段是否在文件中
                if v in lis_title:
                    n.append(lis_title.index(v))
            if '*' in lis[1]:n=[0,1,2,3,4]#定义使用*模糊查询
            if n == []: #如果字段不存在则退出程序
                print('查询的字段不存在')
                return
            if lis[4] == '>':#检查条件语句是否是大于号
                if lis[3] in lis_title: #字段是否包含条件语句
                    m = lis_title.index(lis[3]) #m表示符合条件语句的字符串所在列表位置
                else:
                    print('字段不含有该条件')
                    return
                for v in f:
                    lis_f = v.split(',')#把取出来的每条数据都转化成列表
                    lis_f = [s.strip() for s in lis_f] #列表推导式，去掉每个元素两边的空格
                    if lis_f[m].isdigit() and lis[5].isdigit():#检查条件是否都为数字
                        if int(lis_f[m]) > int(lis[5]):
                            for i in n:#如果条件成立则把结果追加到lis_res中
                                lis_res[i].append(lis_f[i])
                    else:print('无法进行比较')
            elif lis[4] == '<pre class="brush:php;toolbar:false">请输入查询语句，格式为：select *** where *** > ***select * where phone like 188
1  tom  25  18888888888  it
