Complex ()() Function in Python

This guide covers complex ()() function in python with practical context and easy-to-follow details. Use it to understand the subject and apply the information confidently.

Complex ()() Function Syntax in Python

 complex ([phanthuc [, phanao]]) 

Complex Function Parameters ()()

Complex Has two parameters:

• Phanthuc: The real part of the complex number returns, if this parameter is left blank, Python defaults to 0.
• Phanao: The virtual part of the complex number returns, if this parameter is left blank, Python defaults to 0.

If the first parameter passed into Complex Is a string, it will be interpreted as a complex number. In this case you should not pass the second parameter.

The Value Returned from Complex ()()

The Complex () Function returns a complex number.

If the string is passed into a function that is not a complex number, an exception (exception) ValueError Will occur .

Note: The transmitted string must be in Phanthuc + phanaoj or Phanthuc + phanaoJ format.

Example 1: How to create complex numbers in Python

z = complex(2, -3)
print(z) 

z = complex(1)
print(z)

z = complex()
print(z)

z = complex('5-9j')
print(z)

Run the program, the result is:

 (2-3j) 
 (1 + 0j) 
 0j 
 (5-9j) 

Example 2: Complex numbers do not use complex () function

In Python, you can create a complex number without using the Complex () Function .

To do that, you must put 'j' or 'J' After some to Python identity.

a = 2+3j
print('a =',a)

b = -2j
print('b =',b)

c = 0j
print('c =',c)

The output returned is:

a = (2+3j)
b = (-0-2j)
c = 0j
