The previous exercise used random to choose a random number. In this exercise (also available as a PDF) we choose random words from lists to create custom usernames. This exercise introduces the following concepts:
- String Manipulation
- Lists
- For Loops
Type the code below into a new repl.it or use an Python IDE (code editor) such as PyCharm or IDLE.
import random
list_of_nouns = ['form', 'blinkers', 'dune', 'storm', 'thunder', 'lightning', 'cross', 'knife', 'sword', 'jewel', 'diamond', 'ruby', 'sapphire', 'gem']
list_of_adjectives = ['terra', 'red', 'sharp', 'dull', 'high', 'low', 'silent', 'quiet', 'purple', 'pink', 'black', 'white', 'blue', 'green', 'sporadic', 'bright', 'slender']
for i in range(20):
random_noun = random.choice(list_of_nouns)
random_adjective = random.choice(list_of_adjectives)
print(random_adjective.capitalize()+random_noun.capitalize())
Think About the Code
- Line 1 imports code to help us choose random numbers
- Line 3: creates a variable named ‘list_of_nouns’. The Data Type is a list – specifically a list if strings
- Line 4 :creates a variable named ‘list_of_adjectives’. The Data Type is a list – specifically a list if strings
- Line 6: We use a for loop to run the next set of code 20 times
- Line 7: We use the ‘choice’ function that comes from the imported ‘random’ code to pick an item from the list of nouns
- Line 8: We use the ‘choice’ function that comes from the imported ‘random’ code to pick an item from the list of adjectives
- Line 9: We print out the randomly chosen adjective and noun but ‘capitalize’ the first letter of each word
- Notice that the code inside the ‘for’ loop is indented to the right to show that the lines below belong to the ‘for’ loop
What Next
- You could ‘import tkinter’ to create a GUI version of this program (solution here)
- Challenge – create a program that allows the user to input a year and the program will check if that year is a leap year
