Would that essentially return the same chance of random values?Īlso, supposing they essentially return the similar randomness in their values, is there a performance difference over larger iterations? Common sense tells me that since the looping choice() jumps right to the chase, but a sample() first stores the values in a new list and that list then needs to be iterated over, looping choice() would be the cleaner and more efficient alternative. Is the behavior of a loop iteration of choice() essentially the same as the returned sample() list? For clarification, a simple example would be a loop that iterates 4 times using choice() and storing the returned values in a list, versus a sample() of 4 the same values. I guess it's a beginner mistake and lack of attention on my part. It somehow slipped past me that sample returned a list. My mistake was in not addressing the derived sample with an index value, so I was essentially attempting mathematics against a list rather than single values from within the list. I think you answered my question pretty well. If you are new to Python programming, I highly recommend this book. We can do the same thing with a list of strings: from random import * Y = sample(items, 4) # Pick 4 random items from the list X = sample(items, 1) # Pick a random item from the list To pick a random number from a list: from random import * We can shuffle a list with this code: from random import *
To generate a random floating point number between 1 and 10 you can use the uniform() function from random import * X = randint( 1, 100) # Pick a random number between 1 and 100. If you want to store it in a variable you can use: from random import * Print(randint( 1, 100)) # Pick a random number between 1 and 100. To generate a whole number (integer) between one and one hundred use: from random import * Generate a random number between 1 and 100 Print(random()) # Generate a pseudo-random number between 0 and 1. We can generate a (pseudo) random floating point number with this small code: from random import * Python Programming Bootcamp: Go from zero to hero Numbers generated with this module are not truly random but they are enough random for most purposes. The function random() generates a random number between zero and one. Using the random module, we can generate pseudo-random numbers.
