What is wrong with my cod? I couldn't pass lesson in Python introduction course.

Question

# Принимаем число в качестве ввода
number = int(input())
number =3

# Используем цикл while для обратного отсчета
while number >=0:
print(number)
number -=1
# Конец цикла

number =5
while number >=0:
print(number)
number -=1

Answer 1

Andrey Kan ,

i can not find this exercise in the `introduction to python` tutorial.

but it looks that this execise should produce a `countdown` from a given number (from the input) to 1? or 0?.

this is *your* code, but without all non-essential code parts:

number = int(input())

while number >=0:
print(number)
number -=1

> so it would be great if we could get a precise task description.

> can you please check the conditional in the header of the while loop:
should the countdown run until 0 or until 1? (currently it runs until 0)

Answer 2

Daniel Imanaliev ,

the code you have shown has a bug in line 1

Answer 3

Lothar The exercise is only available for users with pro membership, that's why you can't find it. I found it, and the code snippet with the number input in your comment is correct.

Answer 4

Jan ,

i suppose that you (as a pro member) can see the task description.

Andrey Kan is talking about 2 countdowns that has to be done.

maybe there are 2 samples that are shown, but i believe that only one input for a number has to be done, and one code that uses the various inputs.
can you confirm this?

anything else does not make much sence.

Answer 5

Jan ,

thanks a lot!

Andrey Kan , so now it should be possible to solve the task with one input procedure, and with one following code to output numbers from N (input number) to 0.

Lothar , Luo Shenshi , Jan , thanks a lot for your help and support! I really appreciate your assistance! 🙏

Answer 8

Can you explain further more.. like what exactly are you trying to do, cuz you've used "number" 3 times as variable and idk how am I supposed to help...

Answer 9

Sorry guys. The task is:

Create a timer program that will take the number of seconds as input, and countdown to 0. There are two countdowns should be created from 3 to 0 and then as separate another one from 5 to 0.

Answer 10

# Take input from the user for the initial countdown
number = int(input("Enter the number of seconds to countdown from: "))

# Countdown from the user input to 0
while number >= 0:
print(number)
number -= 1

# Countdown from 3 to 0
number = 3
while number >= 0:
print(number)
number -= 1

# Countdown from 5 to 0
number = 5
while number >= 0:
print(number)
number -= 1

should be working now 😊

Answer 11

Lothar Yes, those two countdowns are just examples of what the output could be with different inputs.

Answer 12

Daniel Imanaliev rakhmet bro!

Answer 13

Daniel Imanaliev Your input is wrong, because you are missing a parenthesis.

It should look like this.....

number = int(input())

Answer 14

Счетчик number и ввод тоже number, поменяй имя переменной ввода. цикл while number не может не сравниваться с нулем поставь счётчик вместо нуля. А вообще лучше убери number =3. Зачем оно тебе? Если есть ввод.

Answer 15

# First countdown from 3
number = 3
while number >= 0:
print(number)
number -= 1

print() # Separator for clarity

# Second countdown from 5
number = 5
while number >= 0:
print(number)
number -= 1

This is the right code for the above given code.

Answer 17

Daniel Imanaliev, Dave John Thanks a lot!

Answer 18

maybe there's a syntax error, or maybe you forgot to add an indent? try copying .
