Python 如何在运行时修复语法错误

Question

If I receive a string below with syntax error from a noSQL db that stores it in this exact format, how can I assign it to a variable and "correct" the syntax error during runtime. With assumptions that I cannot change how it is stored on a database.

Since this is a syntax error I can't even use string functions like replace or regex to remove the extra quotations enclosing the phone number.

string = "John Doe "(123) 456-7890""

Desired final result would be for it to not throw a syntax error and compile. I'd appreciate any help I can get. Thanks.

Answer 1

That string assignment indeed throws a SyntaxError if executed as part of your code, but it's not an error for that string to be read from from a database.

In which case it works just as if you had single-quoted the string:

string = 'John Doe "(123) 456-7890"'

Answer 2

It works if you escape the internal quotes with '\' or enclose string with single quotes.

string_param = 'John Doe "(123) 456-7890"'.replace('"', '')

if it's multi-line string, you can use this -

string_param = """
'John Doe "(123) 456-7890"'.replace('"', '')
""".replace('"', '')
