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)

Python code to get the complex number

Python代码获取复数

# python code to demonstrate example 
# of complex() function
real = 10
img  = 20
# complex number  by passing real number
print(complex(real))
# complex number  by passing real & img. number
print(complex(real, img))
# complex number by passing real part as 0
print(complex(0))
# complex number by passing real and img. part as 0, 0
print(complex(0,0))
# with float values
real = 10.23
img  = 20.45
# complex number  by passing real number
print(complex(real))
# complex number  by passing real & img. number
print(complex(real, img))

Output

输出量

(10+0j)
(10+20j)
0j
0j
(10.23+0j)
(10.23+20.45j)
