leaving a time delay in python

is there any way to leave a time delay between the execution of two lines of code?

• You can use the sleep() function in the time module. It can take a float argument for sub second resolution.

  from time import sleep
  sleep(0.1) # Time in seconds.
  

  AlberT : is it completely cross plat or there is any kind of issue on Win, for example, I'd have to care about? Thank you in advance.
