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)

IF AND ELSE STATEMENT

  If Statements    These statements are a bit like asking a question. You are telling the computer:  if  something is true,  then  do this specific block of code. Double equals ( == ) is asking the computer to compare if these two things are  exactly  the same.  EXAMPLE :  myName = input("What's your name?: ") if myName == "David":  What is else? IF  the condition is  not  met with the  if  statement, then we want the computer to do the  else  part instead. Likewise, if the condition  is  met in the  if  statement, then the  else  bit is ignored by the computer. The  else  statement must be the first thing  unindented  after the  if  statement and in line with it    EXAMPLE :  myName = input("What's your name?: ") if myName == "David":  print("Welcome Dude!")  print("You're just the baldest dude I've ever seen...
