FOR LOOP , RANGE

  FOR LOOP 

A while loop is perfect to use when we don't know how many times we want the loop to repeat. 

If we have an idea of how many times we want the loop to repeat, we can use a for loop to loop code in exactly the same way the while loop did. 



EXAMPLE : 

for counter in range(10):
  print(counter)


RANGE 


The range function creates a list of numbers in the range you create. If you only give it one number, it will start at 0 and move to a state where the final number is one less than the number in the brackets. In this case, the final number would be 9. 

EXAMPLE : 

total = 0
for number in range(100) :
  total += number
  print(total)

OS LIBRARY , TIME LIBRARY

  What is the os library? It allows us to "talk" to the console. One of the most powerful things we can do with this library is allow it to clear the console EXAMPLE: import os print("Welcome") print("to") print("Replit") os.system("clear") username = input("Username: ")  Time Library We can import a second library by placing a  ,  after the name of the first library. EXAMPLE: import os, time print("Welcome") print("to") print("Replit") time.sleep(10) os.system("clear") username = input("Username: ")  NOTE:  from replit import audio import os, time def play():   source = audio.play_file('audio.wav')   source.paused = False # unpause the playback   while True:     stop_playback = int(input("Press 2 anytime to stop playback and go back to the menu : ")) # giving the user the option to stop playback     if stop_playback == 2:       source.paused = True # let'...

ALL ABOUT WHILE LOOP

 WHILE LOOP  A  while  loop allows your code to repeat itself based on a condition you set.   EXAMPLE : counter = 0 while counter < 10:   print(counter)   counter +=1 Infinite Loop  You have to be  really  careful that you don't accidentally invoke an infinite loop! This is where the computer will loop code until the end of time. Without a break. Forever.  This is just saying "count to 10 by 1 each time." to make the loop end. Don't forget, if your  condition  is a  >  then you might need to  -= . This will subtract from the variable instead of adding to it.   EXAMPLE : counter = 0 while counter < 10:   print(counter)    counter += 1
