Modify default separators in json.dump in python 2.7.1

In a json.dump method (python 2.7.1) the output has the default separator as (',' and ': '). I want to remove the comma and the colon so that my outputs are simply separated by white space.

I also want to remove the opening and closing braces. Is there any particular attribute of separator or string formatting that allows me to do this or is there any other solution?

For example after applying

with open(foutput, 'a') as f1:
json.dump(newdict, f1,sort_keys=True,indent=4)

I am getting output as :


"0.671962000": 51.61292129099999,
"0.696699155": 51.61242420999999,
"0.721436310": 51.610724798999996,
"0.746173465": 51.60536924799999,
"0.770910620": 51.58964636499999,
"0.795647775": 51.543248571999996,
"0.820384930": 51.381941735,



But I want the below type output instead of that:

0.671962000 -28.875564044
0.696699155 -28.876061125
0.721436310 -28.877760536
0.746173465 -28.883116087
0.770910620 -28.898838970


Please note I only want this in python.
Thanks in advance!

You are not producing JSON, so don't use the JSON module. You are producing CSV data, with a space as delimiter. Use the csv module, or use simple string formatting.

csv

Using the csv module:

csv

import csv

with open(foutput, 'a', newline='') as f1:
writer = csv.writer(f1, delimiter=' ')
writer.writerows(sorted(newdict.items()))


or simply using string formatting:

with open(foutput, 'a') as f1:
for key, value in sorted(newdict.items()):
f1.write(' n'.format(key, value)


'ab'

csv
