complex() function is used to find the a complex number in Python for the real and imaginary parts as the given inputs.
complex() function is a part of Python Built-in Functions.
Syntax of complex() Function
The syntax of complex() function in Python is:
complex([real[, imag]])
Parameters of complex() Function in Python
complex() takes two parameters.real – Where real is a real part and its default value is 0 if real is omitted.imag – Where imag is a imaginary part and its default value is also 0 if imag is omitted.
Compatibility
complex() function is available and compatible with both Python 2.x and 3.x.
Return Value of complex() Function in Python
complex() function returns a complex number with the value in the form of real + imag*1j for the given inputs.
complex() Function Exception
complex() function throw a ValueError exception if the passed string is not a valid complex number.
Python complex() Function Example 1
x = complex(6, -2)
print(x)
x = complex(1)
print(x)
x = complex()
print(x)
x = complex('8-3j')
print(x)
Output:
(6-2j)
(1+0j)
0j
(8-3j)
Python complex() Function Example 2
x = 9+2j
print('x =',x)
print('Type of x is',type(x))
y = -6j
print('y =',y)
print('Type of y is',type(y))
z = 0j
print('z =',z)
print('Type of z is',type(z))
Output:
x = (9+2j)
Type of x is <class 'complex'>
y = (-0-6j)
Type of y is <class 'complex'>
z = 0j
Type of z is <class 'complex'>
