Exercise

Using the argv module, create a script that takes two arguments and prints the sum of the two numbers.

num_1 = int(sys.argv[1])

num_2 = int(sys.argv[2])

sum = (num_1 + num_2)

print(sum)

print(os.getcwd()) # This method returns the current working directory.

os.mkdir('new_dir') # This method creates a new directory.
os.rename('new_dir', 'new_dir_2') # This method renames a file or directory.

'''
You have been tasked to create a random number guessing game.
The game should generate a random number between 1 and 20 (inclusive).

Instructions:
- Ask user to pick range of numbers (min and max)
- Generate a random number between the min and max then store it in a variable
- Ask user to guess a number
- Compare user's guess to the random number generated
- If user guesses correctly, print "You win!"
- If user guesses incorrectly, print "You lose!"
