Python txt File Read and Write Dictionary (json, eval)

Use the json conversion method

1. The dictionary is written into 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. Read the dictionary in txt

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

Use the str conversion method

1. The dictionary is written into 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))      # Convert a dictionary into str
fw.close()

2. Read the dictionary in txt

fr = open("test.txt",'r+')
dic = eval(fr.read())   # Read str Convert to a dictionary 
print(dic)
fr.close()
