#对列表排序
list = [22,4,6,8,10,334,779,234,54,666]
list.sort()
print(list)

#写入列表到文件

with open("txt","w") as f:

    f.write('\n')
    f.write(str(list))

#追加反序到文件下一行

with open('txt','r') as f:

    print(t2)
    list.reverse()
    with open("txt",'a') as f:

         f.write(str(list))
    print(list)
#分别把string，list，tuple，sict写入到文章中
string = 'akgnehkkd123'
tuple = ('a','r','hhh','fe','hty')
list = [23,'ff',456,'ghj','eryi']
dict = {'a':24,'d':56,'cd':89,'b':65}

#将string写入到txt3文件中
with open('txt3','w') as f:
     f.write('\n')
     f.write(string)

#将list写入到txt3文件中
with open('txt3','a') as f:
     f.write('\n')
     f.write(str(list))

#将tuple写入到txt3文件中
with open('txt3','a') as f:
     f.write('\n')
     f.write(str(tuple))

#将dict写入到txt3文件中
