python中以字典为元素的列表怎么写入文本文件

##调用json.dump函数就行了，下面是一个例子

import json

##将FileName指定为你的文件的实际路径

FileName='t.txt'

lst=[{'name':'lili','age':25},{'name':'gg','age':18}]

with open(FileName,'w') as f:

json.dump(lst,f)

##注意：最左边每个=表示一个空格

f='你的文件名.txt'

d={('dsaa','dsa'):1.2132,('fdsfsd','dsada'):2.3243}

with open(f,'w') as fo:

====for k,v in d.items():

========print("%s,%s %.4f" %(k[0],k[1],v),sep='',file=fo)

import pickle

dictfile=open("myfile",'wb')

mydict={"a":[[1,2],[3,4]],"b":[[5,6],[7,8]]}

pickle.dump(mydict,dictfile)

dictfile.close()

dictfile=open("myfile",'rb')

readdict=pickle.load(dictfile)

print(readdict)
