print(long_function('nitu'))

There is no such open mode as 't'. You either want 'w' to write, or 'r' to read the file. Also, the function you want is json.dump, not jsondump. Why are you sleeping for 5 seconds? That will irritate your users. — Tim Roberts

@TimRoberts Mode 't' does exist. It's even the default. Did you maybe look at the documentation for Python 2? — Kelly Bundy

import json
  
# JSON data:
x =  '{ "organization":"New_holn",
        "city":"Noida",
        "country":"India"}'
 
# python object to be appended
y = {"pin":117845}
 
# parsing JSON string:
z = json.loads(x)
  
# appending the data
z.update(y)
 
# the result is a JSON string:
print(json.dumps(z))

This is nothing but follow this pattern and your so your code error is ..you are not defined file mode correctly in if condition

with open (cache_path. "t") as json_file:

Instead of

with open (cache_path. "w") as json_file:

And second thing is you are not doing dump data
