将字符串写入文件 python 时在文件内保留引号

Question

I would like to write file with python

My code is producing:

{ date: 2018-11-28, weight: 172.91, height: 177.65, id:310 }

I want to have the following is the input inside the file

{ date: '2018-11-28', weight: 172.91, height: 177.65, id:310 }

With the single quote mark which I need it to be there.

Any help please for writing string into file with single quote mark '.

my code:

my_dict = { 'date': '2018-11-28', 'weight': 172.91, 'height': 177.65, 'id':310 }
my_dict = str(my_dict)
f = open('file.txt', 'w')
f.write(my_dict)
f.close()

Thanks

Use the JSON library. In your case you would use:

with open('file.txt', 'w') as f:
    json.dump(my_dict, f, indent=4)

Or, to mimic your approach to files:

f = open('file.txt', w)
json.dump(my_dict, f, indent=4)
f.close()
