# How To Write Python Complex Number With Examples

In Python, a complex number is a number with a real and imaginary part represented by `x + yj`, where `x` is the real part, `y` is the imaginary part, and `j` is the imaginary unit (which satisfies the equation `j^2 = -1`). In this article, I will show you how to create complex number in python with examples.

## 1. How To Create Complex Number In Python.

1. You can create a complex number in Python by using the `complex()` function or by directly writing the number in the form `x + yj`.
2. Here are some examples.

### 1.1 Creating complex numbers using complex().

1. Blow example will create 2 complex numbers using the python complex() function.
```>>> a = complex(2, 3)
>>> b = complex(1, -4)
>>>
>>> print(a)
(2+3j)
>>>
>>> print(b)
(1-4j)```

### 1.2 Creating complex numbers directly.

1. You can also use the below python source code to create complex numbers directly.
```d = -3.5 + 0j

print(c)
print(d)

# Below is the output.
(5+2j)
(-3.5+0j)```

### 1.3 Perform arithmetic operations with complex numbers.

1. You can perform arithmetic operations with complex numbers in the same way as you do with real numbers.
```a = 2 + 3j
b = 1 - 4j
print(a + b)
print(a * b)
print(a / b)

Below is the above source code output.

(3-1j)
(14-5j)
(-0.5882352941176471+0.6470588235294118j)```

### 1.4 How to access the real and imaginary parts of a complex number.

1. In addition, you can access the real and imaginary parts of a complex number using the `real` and `imag` attributes respectively.
```a = 2 + 3j
print(a.real)
print(a.imag)

#Below is the above code output.

2.0
3.0```
