python __builtins__ complex类 (13)

13、'complex', 函数用于创建一个值为 real + imag * j 的复数或者转化一个字符串或数为复数。如果第一个参数为字符串,则不需要指定第二个参数。

class complex(object) | complex(real[, imag]) -> complex number | | Create a complex number from a real part and an optional imaginary part. | This is equivalent to (real + imag*1j) where imag defaults to 0.
# 创建一个复数,实数部分是第一个参数,虚部是第二个参数,虚部默认为0. | | Methods defined here: | | __abs__(self, /) | abs(self) | | __add__(self, value, /) | Return self+value. | | __bool__(self, /) | self != 0 | | __divmod__(self, value, /) | Return divmod(self, value). | | __eq__(self, value, /) | Return self==value. | | __float__(self, /) | float(self) | | __floordiv__(self, value, /) | Return self//value. | | __format__(...) | complex.__format__() -> str | | Convert to a string according to format_spec. | | __ge__(self, value, /) | Return self>=value. | | __getattribute__(self, name, /) | Return getattr(self, name). | | __getnewargs__(...) | | __gt__(self, value, /) | Return self>value. | | __hash__(self, /) | Return hash(self). | | __int__(self, /) | int(self) | | __le__(self, value, /) | Return self<=value. | | __lt__(self, value, /) | Return self<value. | | __mod__(self, value, /) | Return self%value. | | __mul__(self, value, /) | Return self*value. | | __ne__(self, value, /) | Return self!=value. | | __neg__(self, /) | -self | | __new__(*args, **kwargs) from builtins.type | Create and return a new object. See help(type) for accurate signature. | | __pos__(self, /) | +self | | __pow__(self, value, mod=None, /) | Return pow(self, value, mod). | | __radd__(self, value, /) | Return value+self. | | __rdivmod__(self, value, /) | Return divmod(value, self). | | __repr__(self, /) | Return repr(self). | | __rfloordiv__(self, value, /) | Return value//self. | | __rmod__(self, value, /) | Return value%self. | | __rmul__(self, value, /) | Return value*self. | | __rpow__(self, value, mod=None, /) | Return pow(value, self, mod). | | __rsub__(self, value, /) | Return value-self. | | __rtruediv__(self, value, /) | Return value/self. | | __str__(self, /) | Return str(self). | | __sub__(self, value, /) | Return self-value. | | __truediv__(self, value, /) | Return self/value. | | conjugate(...) | complex.conjugate() -> complex | | Return the complex conjugate of its argument. (3-4j).conjugate() == 3+4j. | | ---------------------------------------------------------------------- | Data descriptors defined here: | | imag | the imaginary part of a complex number | | real | the real part of a complex number
