That’s why all the numbers in the list are different. Note that the underscore serves as a “throw-away” variable as you don’t actually need it to create the list.Īlso note that the list comprehension statement evaluates the expression multiple times-and not only once in the beginning. ![]() You call it ten times as defined in the context part for _ in range(10). Then, you create a list of random floats by repeatedly calling random.random() that generates a random float number between 0 and 1 each time it is called. In the code, you first import the random module. In my Python shell, the result is the following: print(randlist) # Method 1: List Comprehension Random Float List Context: What elements to select? The context consists of an arbitrary number of for and if statements. ![]() Expression: What to do with each list element?.List comprehension is a compact way of creating lists. Method 1: List Comprehension to Random Float List You can try those yourself in our interactive code shell:Įxercise: Change the interval of each method to and run the code. Method 4: randlist = random.sample(range(20), 10) to create a list of random ints.Method 3: randlist = for _ in range(10): randlist.append(random.randint(0, 99)) to create a list of random ints. ![]() Method 2: to create a list of random ints.Method 1: to create a list of random floats.Solution: Here’s a quick overview on how you can create a list of random numbers: Create a list of n elements in a certain interval (example interval: ). Do you want to initialize a list with some random numbers? In this article, I’ll show you four different way of accomplishing this-along with a short discussion about “the most Pythonic way”.
