Random Number Generator In Python – POFTUT

# Random Number Generator In Python

Python is practical language which provides different functions in practical way. Random number are generally used in security related issues but there are other areas too. In this post we will look different random number generation examples about python.

# Generate Random Number Between 0 and 1

Python provides a library named `random` by default. This library is used to provide different type of random functions according to given parameters. We will use `random` function in order to generate random numbers in this example. This function generates floating point values between 0 and 1

```from random import random
random()```

As we can see produces random numbers are like 0.476250741043003

# Generate Random Number with Randint Between 0 and 10

What if we need to generate integer numbers in specified range. We can not use `random` function in a practical and efficient way. We will use `randint` function in order to generate random numbers between 1 and 10 by specifying range.

```from random import randint
randint(0,10)```

We can see that generated numbers are between 1 and 10

# Generate Random Number with Randint Between 0 and 100

Another useful example is generating random integers between 0 and 100. As you see we can change the range start and end whatever we want.

```from random import randint
randint(0,10)```

# Generate Random Floating Number In Specified Range

We have generated floating random number in 0 and 1 . But we may need more options about the range. For example we may need to generate floating random number between `5.0` and `7.0` . In this situations we will us `uniform` function.

```from random import uniform
uniform(5.0,7.0)
```
Another useful function is `choice` which selects element from given list randomly. We just provide the list and selected element will be returned. In this example we will use `one` , `two` and `three` as a list.
```from random import choice
