Python - Loops?

Question

I was taking the python course here and was confused about something ; loops.

The example was this :
words = ["hello", "world", "spam", "eggs"]
counter = 0
max_index = len(words) - 1

while counter <= max_index:
word = words[counter]
print(word + "!")
counter = counter + 1

I can't understand this, can someone simplify it for me?

Answer 1

Aries

words = list
max_index = length of words -1
max_index = 4 - 1
max_index = 3

Now,
While 0 < 3: means the loop will keep on running as long as this condition is true.
word = words[counter] means:
word = word[0]
word = "hello"
print ("hello" + "!")
counter = 0 + 1
counter = 1 now.
The loop will go to the beginning again.
word = words[counter] means:
word = word[1]
word = "world"...
it will get to a stage when counter will be three, then loop stops.
while 3 <= 3. loop stops here.

Basically all the word in words will be printed with the exclamation mark.

Hope this clarifies some things 😃😃
