Python: Create a list of random integers and select multiple items from the said list

Python module: Exercise-8 with Solution

Write a Python program to create a list of random integers and randomly select multiple items from the said list.

Use random.sample

Sample Solution:

Python Code:

import random 
print("Create a list of random integers:")
population = range(0, 100)
nums_list = random.sample(population, 10)
print(nums_list)
no_elements = 4
print("\nRandomly select",no_elements,"multiple items from the said list:")
result_elements = random.sample(nums_list, no_elements)
print(result_elements)
no_elements = 8
print("\nRandomly select",no_elements,"multiple items from the said list:")
result_elements = random.sample(nums_list, no_elements)
print(result_elements)

Sample Output:

Create a list of random integers:
[46, 4, 45, 50, 43, 85, 74, 42, 99, 7]

Randomly select 4 multiple items from the said list:
[99, 45, 85, 50]

Randomly select 8 multiple items from the said list:
[46, 43, 74, 4, 45, 85, 99, 50]

Python: Tips of the Day

For-else construct useful when searched for something and find it:

# For example assume that I need to search through a list and process each item until a flag item is found and 
# then stop processing. If the flag item is missing then an exception needs to be raised.

for i in mylist:
    if i == theflag:
        break
    process(i)
else:
    raise ValueError("List argument missing terminal flag.")
