Python complex()函数 (Python complex() function)

complex() function is a library function in Python, it is used to get the complex number from given a real number or/and an imaginary number (which is an optional part), it accepts either a real number only or read and an imaginary number and returns a complex number.

complex()函数是Python中的一个库函数，用于从给定的实数或/和虚数(这是可选部分)中获取复数，它仅接受实数，也可以接受读数和虚数数字并返回一个复数。

Syntax:

句法：

complex(real [,Imaginary])

Parameter(s):

参数：

• real – value of a real number

  实数 –实数的值

• Imaginary – an optional parameter, it's default value is 0.

  虚构 –可选参数，默认值为0。

Return value: complex – it returns a complex type of number containing the value in the form of (real + imaginary*j).

返回值： complex –返回复杂的数字类型，其中包含(real +虚数* j)形式的值。

Example:

例：

Input:    real = 10    img  = 20            print(complex(real))    print(complex(real, img))        Output:    (10+0j)    (10+20j)
