[cython/cython] [BUG] Nested double quotes supported by python 3.12 not supported in cython (Issue #6208)
mironleon
Describe the bug
Trying to cythonize an f-string with nested double quotes fails with an error message. This might be wholly intentional and reasonable, but the nested double quotes are valid in python 3.12 and the cython-lint tool automatically formats your code to use them (also filed a bug report for cython-lint)
Error compiling Cython file:
------------------------------------------------------------
...
def function():
a = f"foo [{"bar"}]"
^
------------------------------------------------------------
test.pyx:2:17: empty expression not allowed in f-string
Error compiling Cython file:
------------------------------------------------------------
...
def function():
a = f"foo [{"bar"}]"
^
------------------------------------------------------------
test.pyx:2:17: missing '}' in format string expression
Error compiling Cython file:
------------------------------------------------------------
...
def function():
a = f"foo [{"bar"}]"
^
------------------------------------------------------------
Code to reproduce the behaviour:
def function(): a = f"foo [{"bar"}]" print(a)
Expected behaviour
Cythonizing correctly and when calling the function outputting:
foo ["bar"]
