Complex() Function in Python

Implementation 

There are several ways to show the working complex in Python. Some of them are mentioned below:

Integer Type

• Python

Python

print("Enter the number")
z = input()
print("Complex number is")
print (complex(z))

You can also try this code with Online Python Compiler

Run Code

Output

Float Type 

• Python

Python

p=input("Enter a float:")
complex = complex(p)
print("Complex number is: ", complex)

You can also try this code with Online Python Compiler

Run Code

Output

You can compile it with online python compiler.

Exceptions of complex() in Python

The complex() function in Python can raise exceptions in certain situations. Here are some scenarios where exceptions may occur:

1. Invalid Argument Types: If the complex() function is called with arguments that are not numeric (e.g., strings, lists, or other non-numeric types), a TypeError will be raised.

result = complex("3", "4")  # Raises TypeError

2. Invalid String Format for Real or Imaginary Part: If the function is called with a string argument that doesn't represent a valid numeric value, a ValueError is raised.

result = complex("abc", 4)  # Raises ValueError

3. Too Many Arguments: If more than two arguments are provided to the complex() function, a TypeError is raised.

result = complex(3, 4, 5)  # Raises TypeError

4. Invalid Imaginary Suffix: If a numeric literal is used with an invalid imaginary suffix (other than 'j' or 'J'), a SyntaxError will be raised.

result = complex(3, 4i)  # Raises SyntaxError

Example of complex() in Python

Let us understand complex() function in Python with the help of different types of examples:

1. Basic Example:

• Python

Python

result = complex(2, 3)
print(result)

You can also try this code with Online Python Compiler

Run Code

Output

(2+3j)

2. Using Variables:
 

• Python

Python

real_part = 5
imaginary_part = -2
result = complex(real_part, imaginary_part)
print(result)

You can also try this code with Online Python Compiler

Run Code

Output

(5-2j)

3. Using Numeric Literals:

• Python

Python

result = complex(1.5, -2.5)
print(result)

You can also try this code with Online Python Compiler

Run Code

Output

(1.5-2.5j)

4. String Representation:

• Python

Python

complex_str = complex("2.5+3j")
print(complex_str)

You can also try this code with Online Python Compiler

Run Code

Output

(2.5+3j)

5. Zero Imaginary Part:

• Python

Python

result = complex(7)
print(result)

You can also try this code with Online Python Compiler

Run Code

Output

(7+0j)

Frequently Asked Questions

What is a complex expression in Python?

A complex expression in Python involves multiple operations and data types, often combining arithmetic, logical, or conditional operations in one line.

What is a complex data type in Python?

The complex data type in Python represents numbers with a real part and an imaginary part, written as real+imagj.

What is a complex object in Python?

A complex object in Python is an instance of the complex class, representing numbers with both real and imaginary components.
