There is a need to generate random numbers when studying a model or behavior of a program for different range of values. Python can generate such random numbers by using the random module. In the below examples we will first see how to generate a single random number and then extend it to generate a list of random numbers.
Generating a Single Random Number
The random() method in random module generates a float number between 0 and 1.
Example
Output
Running the above code gives us the following result −
Generating Number in a Range
The randint() method generates a integer between a given range of numbers.
Example
Output
Running the above code gives us the following result −
Generating a List of numbers Using For Loop
Python Codes List
We can use the above randint() method along with a for loop to generate a list of numbers. We first create an empty list and then append the random numbers generated to the empty list one by one.
Example
Output
Running the above code gives us the following result −
Using random.sample()
We can also use the sample() method available in random module to directly generate a list of random numbers.Here we specify a range and give how many random numbers we need to generate.
