Question

How do I get it to print at each second rather than having it all print at once?

Community Answer

Use the time.sleep(x) function. It allows for the program to pause for x seconds. After every print statement, insert time.sleep(1).

Question

Why have the 'time' module if it is never used?

Community Answer

If you write a program for, say, a robot and have the servo controls in milliseconds, then it will use the time module to send the electrical signal for the right amount of time.

Question

I keep getting the following error: "expected an indented block." What have I done wrong?

Community Answer

You need to press the "Tab" key to indent, so if you were doing an "if" loop. you would do: if a = b: print("Indentation is the space before print")

Question

I want to print the time on the video screen. What should I do?

Community Answer

I assume that you mean the Python Turtle Graphics window. If I`m correct, you should use the function "write()" instead of "print()". Then you would have to add "clear()" because "write()" does not change the lines automatically. Otherwise you could move the position of your Turtle. To use the function "write()", you also have to add "from turtle import *".

Question

I'm using LiClipse and when loading the code, it loads, but nothing happens. Indentation is fine and the only thing I have changed is changing the variable n to a.

Community Answer

Check for syntax errors, most commonly a semi-colon at the end of all required phases, and make sure that your OS, drivers, and Python are all latest update. It may also be helpful to check the firewall and see if it's blocking the interface.

Question

How can I stop or abort the countdown?

Community Answer

By using the "break" keyword. For example, if you wanted to initiate a countdown but wanted to stop it halfway through, you could try something like this: i = 10 while i < 10: print(i) i -= 1 if i == 5 break print("done")

How do I create a timer that produces a random number after a set amount of time in Python?

Community Answer

First import random. You can then add this line after the code: random.choice(1,2,3,4,5,6,7,8,9).

Question

How do I run a background timer in a quiz?

Invisible One

Community Answer

This is difficult to do in Python. You should use threading to accomplish this: def laughing: while True: print("Haha") thread1 = threading(laughing) thread1.start()

Question

How can I learn Python in 30 days?

BJW1661

Community Answer

There is no set amount of time to learn Python. However, it can be accomplished in that time. Don’t rush, otherwise you will risk giving up out of frustration. There are no shortcuts, you just need to take your time, learn by doing and you’ll get there.

Question

If i don't want the timer to appear every x second, how do I write the code if I want the user to type the command (eg: !timer) then it ask "How many seconds to count down? Enter an integer:" ?

Simeon Watson

Community Answer

You'd write it as: import time time = int(input("How many seconds to countdown? Enter an integer: ")) time.sleep(time) print("Countdown for", time, "seconds is over!")
