Question

What I am trying to accomplish is first text appears after 1 second. then 2, ect. till 10. then when time equals 10, the time decreases, so the text appears after 9 seconds, then 8 etc.

How could I fix this code so that it works properly?

The error:

Traceback (most recent call last):
  File "C:/Users/Eric/Dropbox/time.py", line 13, in <module>
    time.sleep(time)
AttributeError: 'int' object has no attribute 'sleep'

The code :

import time
x = 1
t = 1
time = t + 1
while x == 1:


    print time
    if time >=10:
        time = t - 1
    elif time <= 0:
        time = t + 1
    time.sleep(time)

---

Edit:

import time
x = 1
t = 1
time1 = 0
while x == 1:

    if time1 == 10:
        time1 = time1 - 1
    elif time1 == 0:
        time1 = time1 + 1
    else :
        time1 = time1 + 1
    print time1
    time.sleep(time1)

So I changed the program around abit, so I almost works correctly. What it does is count to 10, then 9 then back to 10.
ex. 1,2,3,4,5,6,7,8,9,10,9,10,9,10
how can I set it so that the program increases time to ten then decreases to zero then increases again?

You’re overriding the imported time module (line 1) by your own time variable (line 4). You can:

• rename your time variable to something else

  import time
  x = 1
  t = 1
  time_passed = t + 1 # use "time_passed" instead of "time" for example
  while x == 1:
      print time_passed
      if time_passed >= 10:
          time_passed = t - 1
      elif time_passed <= 0:
          time_passed = t + 1
      time.sleep(time_passed)
  

• alias the imported time module with import time as tm the use tm.sleep(time)

  import time as tm # alias the time module as "tm" for example
  x = 1
  t = 1
  time  = t + 1
  while x == 1:
      print time
      if time >= 10:
          time = t - 1
      elif time <= 0:
          time = t + 1
      tm.sleep(time) # use "tm" to refer to the module
  

• only import sleep from time with from time import sleep and use sleep(time) instead

  from time import sleep # only import "sleep" from time, not the whole module
  x = 1
  t = 1
  time  = t + 1
  while x == 1:
      print time
      if time >= 10:
          time = t - 1
      elif time <= 0:
          time = t + 1
      sleep(time) # use "sleep" directly

After fixing this, you also need to somehow remember that you need to either increase or decrease the time at the next iteration. For example:

from time import sleep
x = 1
t = 1
time  = t + 1
incr = True
while x == 1:
    print time
    if time >= 10:
        time = 9
        incr = False
    elif time <= 0:
        time = t + 1
        incr = True
    else:
        if incr:
            time = time + 1
        else:
            time = time - 1
    sleep(time)
