Learning Python: Loops

#1. loop through an array

fruits = ["apple", "banana", "cherry", "dragon fruit"]

print("Example 1: Printing Fruits")
for x in fruits:
    print(x)

Notice there is no begin and end blocks! Indenting implies a block has begun

#2. Loop through a string

a_fruit = "banana"
print("Example 2: Banana in loop")
for x in a_fruit:
    print(x)

#3. Break a loop

print("Example 3: Break example")
print("Fruit Array has these values {0}\n\n".format(fruits))
#^^^^ string interpolation


print("If we are going to break at banana we only"\
    "should be printing an apple\n")
#^^^^  statements that span across multiple lines have backslash
for x in fruits:
    if x == "banana":
        break
    print(x)

#4 For i = 1 to 10

print("Prining Numbers from 1 to 10")
for x in range(10):
    print(x)

print("ooops... :-)")

print("\n let's try again")
for x in range(1, 10):
    print(x)

print("oopss... :-(")

print("\n let's try again")
for x in range(1, 11):
    print(x)
print("Yay! Can you give my computer science engineering certificate")

print("\n. Print odd numbers")

for x in range(1, 11, 2):
    print(x)

print("\n. Print even numbers")

for x in range(0, 11, 2):
    print(x)
