Loops 🔁

Loops repeat work so you do not have to. Python has two kinds.

for: go through each item

for planet in ["Mercury", "Venus", "Earth"]:
    print(planet)

for i in range(5):      # 0,1,2,3,4
    print(i)

for i in range(1, 11, 2):   # 1,3,5,7,9
    print(i)

while: repeat until a condition changes

fuel = 3
while fuel > 0:
    print("Burning fuel:", fuel)
    fuel -= 1
print("Liftoff!")

break and continue

for n in range(10):
    if n == 3:
        continue   # skip 3
    if n == 6:
        break      # stop entirely
    print(n)

enumerate: index and value together

for i, letter in enumerate("abc"):
    print(i, letter)

Your challenge

Print the multiplication table for 7, from 7 x 1 = 7 up to 7 x 5 = 35, one per line, in exactly that format.
