I have a simple python script that outputs to an author.json
file. The problem is that it does not include a newline at the end of the file.
What is the best way to add a newline to the end of author.json
?
#!/usr/bin/env python
import json
with open('input.json', 'r') as handle:
data = json.load(handle)
output = open('author.json', 'w')
author = {}
for key, value in data.items():
if key == 'id':
author['id'] = value
output.write(json.dumps(author, indent=4))
For Python 3.x , you can also use print()
function, it will add the newline for you , so instead of output.write()
, you will do -
print(json.dumps(author, indent=4),file=output)
Example/Demo -
>>> with open('a.txt','w') as f:
... print('asd',file=f)
... print('asd1',file=f)
... print('asd2',file=f)
File a.txt
contains -
asd
asd1
asd2
Add the end of line manually:
output.write('{}\n'.format(json.dumps(author, indent=4)))
I hope you realize that your script will only ever have the last id's value in the output; as you are overwriting the key in your loop (dictionaries cannot have duplicate keys).
So even if you have 5 id
values in the original file, you'll only have one value in the resulting data.
put.write(json.dumps("author\n", indent=4))
