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:
1 | 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
1 2 3 4 5 6 7 8 9 10 11 | 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
1 2 3 4 5 6 7 8 9 10 11 | 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'>
