Your code doesn't look Pythonic as your code does not follow PEP 8.

• A lot of PEP 8 is to do with whitespace; two newlines above and below top level class and function definitions, two spaces in front of an inline comment, a space always after a comma, a single space either side of operators.
• You're using lowerTitleCase rather than snake_case for functions and variable names.
• You have a lot of unneeded parentheses making your code more dense.
• You're inconsistent in your string delimiters.

A couple of these issues and given that you have a function named hello_world makes me think you've clearly taken the Flask code from the web.

You have also used comments rather than docstrings, PEP 257, to document your code.

Your server API doesn't seem too great:

• All responses are 200 OK even in failure where some 400 codes would make sense.

• Your API doesn't have a common format to easily identify if a response was successful whether or not you're not using HTTP codes.

  Your error messages don't even have a common format or word.

In all your code at a short glance has a few red flags.
