[New-bugs-announce] [issue28203] complex() gives wrong error when the second argument has an invalid type

[Manish Goregaokar]

New submission from Manish Goregaokar:

When the second argument of complex() is not a number/string, the type error reports the error but prints the type of the first argument:

    > complex({1:2},1j)
    Traceback (most recent call last):
     File "<stdin>", line 1, in <module>
    TypeError: complex() argument must be a string or a number, not 'dict'
    >complex(1j,{1:2})
    Traceback (most recent call last):
     File "<stdin>", line 1, in <module>
    TypeError: complex() argument must be a string or a number, not 'complex'
    >>> complex(1, {1:2})
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    TypeError: complex() argument must be a string or a number, not 'int'
