random pick from array python code example
Example 1: how to get a random element from an array in python
import random
names=['Mark', 'Sam', 'Henry']
#Set any array
random_array_item=random.choice(names)
#Declare a variable as a random choice
print(random_array_item)
#Print the random choice
#Or, if you want to arrange them in any order:
for j in range(names):
print(random.choice(names))
Example 2: python make a random number
# generate random integer values
from random import seed
from random import randint
# seed random number generator
seed(1)
# generate some integers
for _ in range(10):
value = randint(0, 10)
print(value)
Example 3: print random string from list python
import random
list = ["Item 1", "Item 2", "Item 3"] # List
item = random.choice(list) # Chooses from list
print(item) # Prints choice
# From stackoverflow
# Tried and tested method
Example 4: how to generate random character from an array js
function makeid() {
var text = "";
var possible = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";
for (var i = 0; i < 5; i++)
text += possible.charAt(Math.floor(Math.random() * possible.length));
return text;
}
console.log(makeid());
Example 5: select random value from list python
import random
# with replacement = same item CAN be chosen more than once.
# without replacement = same item CANNOT be chosen more then once.
# Randomly select 2 elements from list without replacement and return a list
random.sample(list_name, 2)
# Randomly select 3 elements from list with replacement and return a list
random.choices(set_name, k=3)
# Returns 1 random element from list
random.choice(list_name)
