Python complex() class

Python complex() class The complex() class in Python returns a complex number or converts a string or number to a complex number. Syntax

class complex([real[, imag]])

Parameter Real: This parameter consists of a number representing the real part of the complex number. By default, its value is 0. The real number can also be a String, like this '3+5j', when this is the case, the second parameter should be omitted. Imaginary: It is an optional parameter which consists of a number representing the imaginary part of the complex number Return It returns a complex number by specifying a real number and an imaginary number. Example 1

# Python Program explaining
# complex() class
val1 = complex(11) # Passing single parameter 
val2 = complex(11,12) # Passing two parameters 
# passing the output
print(val1) 
print(val2)

Output

(11+0j)
(11+12j)

Example 2

# Python Program explaining
# complex() class
val1 = complex(1.5) # Passing single integer parameter 
val2 = complex(1.5,2.2) # Passing double integer parameters  
# passing the output
print(val1) 
print(val2)

Output

(1.5+0j)
(1.5+2.2j)

Example 3

# Python Program explaining
# complex() class
val1 = complex(1+2j)
val2 = complex(1+2j,2+3j)
print(val1) 
print(val2)

Output

(1+2j)
(-2+4j)
