This might be a dumb question, but I type this code in, named the file python.masterticket.py just like the video, typed it into the console, and it says command not recognized?

Code -

TICKET_PRICE = 10

tickets_remaining = 100

Output how many tickets are remaining using the tickets_remaining variable

print("There are {} tickets remaining.format(tickets_remaining))

Gather the user's name and assign it to new variable

name = input("What is your name? ")

Prompt the user by name and ask how many tickets they would like.

num_tickets = input("How many tickets would you like {}? ".format(name)) num_tickets = int(num_tickets)

Calculate the price of the tickets (Number of tickets x price per ticket) and shown the cost

amount_due = num_tickets * TICKET_PRICE

Output the cost on screen.

print("The total cost is {}".format(amount_due))

Console -

treehouse:~/workspace$ python.masterticket.py

Press "Enter/Return And this returns: **

bash: python.masterticket.py: command not found
