pylint #37842 detect UnboundLocalError: local variable referenced before assignment [open]

This is a quite common Python error, which can be triggered by:

  • a wrong name shadowing an other one
  • a missing initialization path (variable is initialized in the if branch but not in the else branch)
  • ...

Having pylint detecting this would be very nice.

    The following code is obviously wrong but pylint 0.25.1 won't see it:

    def main():
    """Main"""
    condition = False
    if condition:
    quux = 3

    string = '{quux}' if condition else 'foobar'
    print string.format(quux=quux)
