how do i request and export http file if to read file is not present in my directory. my Code
def data():
try:
with open('sample.json', 'r') as openfile:
json_object = json.load(openfile)
except FileNotFoundError as e:
print(e)
else:
print('Downloading NOW...')
url = 'https://margincalculator.angelbroking.com/OpenAPI_File/files/OpenAPIScripMaster.json'
d = requests.get(url).json()
with open("sample.json", "w") as outfile:
json.dump(d, outfile)
print('sym downloaded')
finally:
with open('sample.json', 'r') as openfile:
json_object = json.load(openfile)
print(json_object)
What am i trying?
step 1 : Try : Read file from directory
step 2 : if file not found in directory than get it from url and export
step 3 : than read again
step 4 : if still erorr than print('Error in code Please Check')
else print the read_file
thank you for taking your time to response to my question

Code:
- Use
isfile(<file>)
instead, it is a better option in this case. isfile('sample.json')
checks if file exists or not.
from os.path import isfile
def data():
file='sample.json'
if isfile(file):
with open(file, 'r') as openfile:
json_object = json.load(openfile)
else:
print('Downloading NOW...')
url = 'https://margincalculator.angelbroking.com/OpenAPI_File/files/OpenAPIScripMaster.json'
d = requests.get(url).json()
with open("sample.json", "w") as outfile:
json.dump(d, outfile)
print('sym downloaded')
with open('sample.json', 'r') as openfile:
json_object = json.load(openfile)
print(json_object)
