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
But how can i make it generate a number that is positive or negative, when i change it to a = (rand%10)-10; b = (rand%10)-10; it makes it always negative. I want to generate two numbers and have them either one or the other or neither or both be negative, randomly. Generate Random Numbers in C. To generate random numbers in C programming, use the function rand to generate and print random numbers. And if you want to generate different-different random numbers at each time when you compile and run the same program, then use the function srand before generating the random numbers using the function rand as shown here in the following program. The Random.Next method returns a random number in C#. The Random class's RandomByte and RandomDouble method returns a random byte and and a random double integer. The code examples show how to generate a random string and random integer in C# and.NET. C library function - rand - The C library function int rand(void) returns a pseudo-random number in the range of 0 to RANDMAX.
The random() method in random module generates a float number between 0 and 1.

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.

Running the above code gives us the following result − Vista home premium key generator.
Generating a List of numbers Using For Loop
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.

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.
