# Create a Random Password Generator using Python

Hello world!

We all make use of passwords on a daily basis, to keep your account safe and prevent your password from being hacked we have to make our password is hard enough that nobody can guess.

Password generator is a Random Password generating program which generates a password mix of upper and lowercase letters, as well as numbers and symbols strong enough to provides great security.

In this Blog article, we will learn how to **Create a Random Password Generator.** We will see the implementation in Python.

## What will be covered in this Blog

```python
1. What is Password
2. Random and String Module
3. how to Create a Random Password Generator
```

Let's get started!

## What is Password:

A password, sometimes called a passcode, is a memorized secret, typically a string of characters, usually used to confirm the identity of a user, In other words is a string of characters used to verify the identity of a user during the authentication process.

If you wish to know more about it, you can refer to [Password Wikipedia Page](https://en.wikipedia.org/wiki/Password). 

## Modules Used: 

### Random Module:

Random module is used to perform the random generations. We are making use of `random.sample` module here. If you will observe in the output all characters will be unique. `random.sample()` never repeats characters. If you don’t want to repeat characters or digits in the random string, then use `random.sample()` but it is less secure because it will reduce the probability of combinations because we are not allowing repetitive letters and digits.

### String Module:

The [string module](https://www.pythonforbeginners.com/basics/strings) contains a number of useful constants, classes and a number of functions to process the standard python string.

1. **`string.ascii_letters`**: Concatenation of the ascii (upper and lowercase) letters
2. **`string.ascii_lowercase`**: All lower case letters
3. **`string.ascii_uppercase`**: All Upper case letters
4. **`string.digits`**: The string ‘0123456789’.
5. **`string.punctuation`**: String of ASCII characters which are considered punctuation characters in the C
   locale.

Now that you are familiar with password use cases and have acquired basic knowledge of `random` and `string` module, we can move forward to the coding section. 

## Time to Code!

You can find all the code at my [GitHub Repository](https://github.com/ayushi7rawat/Youtube-Projects/tree/master/Random%20Password%20Generator). **Drop a star** if you find it useful.

In order to access the Python library, we need to import the package in our Python script.

```python
import random
import string
```

Once done, let's greet the user!

```python
print('hello, Welcome to Password generator!')
```

Next, let's ask the user for the length of the password.

```python
length = int(input('\nEnter the length of password: '))                      
```

Its time to define the data. We will make use of `string` module for the same.

````python
lower = string.ascii_lowercase
upper = string.ascii_uppercase
num = string.digits
symbols = string.punctuation
````

We have stored lowercase and uppercase letters along with numbers and symbols. Let's combine the data and store the data.

```python
all = lower + upper + num + symbols
```

Now that we have the data, let's make use of `random` module to finally generate the password.

```python
temp = random.sample(all,length)

password = "".join(temp)
```

We are passing in the the combined data along with the length of password, and joining them at the end.

Now that you have a clear understanding of the script, we can even reduce the number of lines of code by eliminating the storage of data. Let's have a look.

```python
all = string.ascii_letters + string.digits + string.punctuation
pass = "".join(random.sample(all,length))
```

Finally, let's print the password!

```python
print(password)
```

Let's have look at few sample outputs:

```
#SAMPLE O/P: (length = 16)

3Atza*qP#h-vJoK+
7c%A4gOt#M[}qr2
@JmFf"awbQ1Ts4dx
```


With these steps, we have successfully created a random password generator project using python. That's it!
