Generate Random Numbers | Python Tutorial for Beginners | Coding Interview Questions & Answers

Key Takeaways

look at some point when you are doing real life projects in Python you need to Generate random numbers for some specific work there are quite a few ways to do this and here we will discuss four different ways of generating random numbers depending upon various use cases that you may come across for generating random numbers python has an inbuilt module called random so right at the onset we are importing it as first use case let's say you want to print a single random value which is a float between zero and one uh for that we use uh the random method let's run this and as you can see we get a float between 0o and 1 uh using this method random moving on to the second use case let's say you want to print a float between a specific range let's say 1 and 100 for that we use the uniform method let me run this and as you can see we are getting a float value but this time between 1 and 100 as third use case let's say you want to print a random integer this time again in a specific range for that we use uh the method Rand in let me run this and as you can see we are getting uh a random integer this time between the specified range if I run it again again we are going to get a different random integer moving on let's say our use case is to uh generate a random number in a range with incremental steps for that we use the Rand range method it has start which is this a stop which is this and the step we can use this to print random uh even or odd numbers in a given range for example let's say we want to print even numbers uh between 0 and 100 in that case I'll Define my step to be equal to two and every time I just generate a random number with this uh line of code I'll always get an even number all right moving on to the last use case all of these uh codes that we have discussed till now give a single random number every time we call them now to print a series of numbers randomly uh we use the sample method for using the sample method we first of all Define a range again let's say between 0 and 100 and the number of random numbers that we want to generate dat if I run this one we'll get three random numbers generated so that is all about random numbers next time when you are asked about how to print random numbers I hope you can answer that question
