Python comes with a set of functions useful for generating or manipulating random numbers. The randomness in Python is useful for developing different types of games, lotteries, or other applications dependent on random number generation.

Randomness is an essential concept in programming, allowing for unpredictable and non-deterministic behavior. In Python, randomness is commonly achieved using the random module, which provides functions for generating random numbers, selecting random elements, and shuffling sequences.
To work with random numbers, you can use the following functions from the random module:
Here’s an example that demonstrates the usage of randomness in Python:
In this example, we use random.randint() to generate a random number between 1 and 10, random.random() to generate a random float between 0 and 1, random.choice() to select a random element from a list, and random.shuffle() to shuffle the elements of a list. These functions showcase the randomness capability offered by the random module in Python.
The random module in Python comes with functions useful for generating random numbers according to the coder’s requirements. Every time a code is run, the random number generator won’t give different numbers. But the value generated cannot be predicted beforehand.

The random.randint() function is useful for generating a random number within the range specified by the programmer. The function will provide a random number in the form of an integer data type. The random.randit() function is available in the random module, which must be imported for this function to take place.
The code for generating a random integer between 0 to 1 using the random.randit() is as follows:
The random.random() function of a random module can generate a random float number from the 0.0, 1.0 semi-open range. The syntax for it is as follows:

The Gauss () function is useful for drawing random floating points from a Gaussian distribution. The function considers two arguments corresponding to the parameters. These parameters control the size of the distribution, particularly the mean and the standard deviation.
Check out this example to generate 10 random values from a Gaussian distribution with a 0.0 mean and 1.0 deviation.
The random number generator Python also uses the uniform distribution inversion method to deliver outcomes. The syntax for using the rand to get 1000 random numbers via uniform distribution on the interval is as follows:
If you want to make a sequence of random numbers reproducible, you need to set the random number seed generator using the set.seed(). Take a look at the below example:
