For Loops: Code: print("print 0 - 4")
for i in range(5): # for each number i in range 0-4. range(5) function returns list [0, 1, 2, 3, 4]
print(" ", i) # this line is executed 5 times. First time i equals 0, then 1, ...
primes = [2, 3, 5, 7] # create new list
print("new list is ", primes)
for p in primes: # for each number in "primes" print
print(" ", p)
Output: print 0 - 4

While Loops: Code: square = 0
number = 0
while number < 10:
square = number ** 2
print("square of ", number, "is", square)
number += 1
Output: square of 0 is 0
square of 1 is 1
square of 2 is 4
square of 3 is 9
square of 4 is 16
square of 5 is 25
square of 6 is 36
square of 7 is 49
square of 8 is 64
square of 9 is 81
