一、使用json转换方法
1、字典写入txt

import json

dic = {
'andy':{
'age': 23,
'city': 'beijing',
'skill': 'python'
},
'william': {
'age': 25,
'city': 'shanghai',
'skill': 'js'
}
}

js = json.dumps(dic)
file = open('test.txt', 'w')
file.write(js)
file.close()

2、读取txt中的字典

import json

file = open('test.txt', 'r')
js = file.read()
dic = json.loads(js)
print(dic)
file.close()

二、使用str转换方法
1、字典写入txt

dic = {
'andy':{
'age': 23,
'city': 'beijing',
'skill': 'python'
},
'william': {
'age': 25,
'city': 'shanghai',
'skill': 'js'
}
}

fw = open("test.txt",'w+')
fw.write(str(dic)) #把字典转化为str
fw.close()

2、读取txt中字典

fr = open("test.txt",'r+')
dic = eval(fr.read()) #读取的str转换为字典
print(dic)
fr.close()
