Loops in Python

for ch in "abc":
    print(ch)

for i in range(3):      # 0, 1, 2
    print(i)

n = 3
while n > 0:
    print(n)
    n -= 1

for n in range(2, 10):
    if n % 2 == 0:
        continue        # skip even numbers
    if n > 7:
        break           # stop the loop
    print(n)
else:
    print("loop finished without break")

names = ["Asha", "Ravi"]
for index, name in enumerate(names, start=1):
    print(index, name)

for a, b in zip([1, 2], ["x", "y"]):
    print(a, b)
