Make a loop that goes through the list and checks the word lengths.Therefor I naively decided to use word length as an indicator of what the price should be. Since I've never opened a business before I have no clue as to what the prices could be. I would like to assign a price to my items. Make a list containing the different items I could sell.If the value is any other value it should print 'good'.If the value is 1 it should print 'better'.If the value is 0 it should print 'failure'.Make a loop that goes through the list and checks the values:.Otherwise a green gift is printed if the baby's gender is still unknown/ neither male nor female. A blue gift is printed if the baby is a male, and a purple gift is printed if the baby is a female. In the example above the loop goes through each name in the list and performs the correct commands. Now I will use the if, elif and else sentence and add some conditions. First I will give some random baby names a gender value and then create a list containing the names. So let's try out the if, elif and else sentences with a loop. Even the if-else sentences can be put into them! There are lots of operations that can be done in loops. If, elif, else sentences combined with the for loop For example we could ask it to print each word in the list and print the length of each word in the list: for i in my_list: We could also ask the loop to do two commands at once. And then we could turn it into a loop that prints out the newly split words in the list! my_list = 'Hi there! How are you?'.split() So with a sentence, it would divide it up where there is a space between the words. If we want we can use the split() function that divides a string into segments by white space.

In the example below you can see the code for creating this for loop. Notice that all the stuff we want to take place in a iteration of the loop has to be indented by one tabulator, so it goes from 0-9 instead of 1-10.Īnother for loop goes through all the items in a list, and simply prints them out. i represents the output in each loop here, so if we print(i) and have a look at the output Shell, we get the numbers: 0 1 2 3 4 5 6 7 8 9. The range(10) is a command, that loops 10 times and produces a number starting from 1 for each loop. I've just named it 'i' here because it's commonly used in programming. The i in the code, represents each item in the list and I can name it anything I want. In the loop above, the word for is the command that initiates the loop. The most simple for loop creates a list of numbers. Or we might want to add a measurement to a list for every iteration in the loop. We could use a for loop to go through 200 images and collect responses for each image. For example it could allow us to go through all items in a list and perform an operation on each item. For loops are loops that allow us to repeat a procedure multiple times. In each iteration, get the value of the list at the current index using the statement value = my_list.Let me introduce you to for loops.Loop variable index starts from 0 in this case. Using a for loop, iterate through the length of my_list.You can access the index even without using enumerate(). The value of the parameter start provides the starting index.Įxample 3: Without using enumerate() my_list = If you want to learn more about enumerate(), please visit Python enumerate().Įxample 2: Start the indexing with non zero value my_list = įor index, val in enumerate(my_list, start=1): The function of enumerate() is to add a counter (i.e.

  • Print the required variables inside the for loop block.
  • You can give any name to these variables.
  • Pass two loop variables index and val in the for loop.
  • Using enumerate(), we can print both the index and the values.
