Programatically adding escape characters to Python List

Question

I have a Python list:

instrumentList=["44433141537", "192797680391", "192773331481", "44433141641", "44434295873"]

I want to write this list to a text file and escape the " characters. The final output I am looking for is:

[\"44433141537\", \"192797680391\", \"192773331481\", \"44433141641\", \"44434295873\"]

This string will ultimately end up being concatenated between two further [static] strings that I have manual escaped - the overall string is a graphQL query that is passed to a GraphQL API endpoint which needs quote marks and line feeds escaped.

I've tried:

escapedInstrumentList={json.dumps(instrumentList).replace("'","\'")}

but this outputs:

"[""44433141537"", ""192797680391"", ""192773331481"", ""44433141641"", ""44434295873""]"

Any guidance gratefully received.

Answer 1

Please try this:

instrumentList=["44433141537", "192797680391", "192773331481", "44433141641", "44434295873"]
json.dumps(instrumentList).replace('"', '''\\"''')

Answer 2

If you want to convert your list of strings to a string that can be printed to a text file you can use this:

instrumentList=["44433141537", "192797680391", "192773331481", "44433141641", "44434295873"]

output = '['+ ', '.join([f'\\"{item}\\"' for item in instrumentList]) + ']'

print(output)

Output as requirement.

Answer 3

import json, re
instrumentList=["44433141537", "192797680391", "192773331481", "44433141641", "44434295873"]
escapedInstrumentList= {re.sub('"', '/"', json.dumps(instrumentList)) }
print(escapedInstrumentList)

Try this one.
