Python Loops
Basic For loop
for x in range(10):
print(x)
- This will repeat the code below it 10 times, and the count will be stored in the variable x (0 through 9).
For loop in a range
for x in range(10,20):
print(x)
- This will loop from 10 up to (but not including) 20.
For loop through array values
myArray = [2,5,2,4,7,3,2,9,1]
for x in myArray:
print(x)
- This will loop through each of the values in the list provided, x takes on that value in each repetition.
While loop
x = 0
while x < 5:
print(x)
x = x+1
- This will continue repeating while a condition is met.
- The while loop is useful when you are checking a condition rather than a count.
- Be careful not to set a condition that cannot be met, otherwise it will keep repeating until it runs out of memory.
Challenge
Create a loop that displays every multiple of 12 up to the 50th.
