I have an empty list which is continuously being appended when data is inputted via the input function e.g.

x = []

After the first input, the list will be automatically appended to something like this: x = [CAR]

how do I format the list to show something like this:

>>>Encryption 1: CAR

Then after the second input, the list will show :

x = [CAR, SHIP]

>>>Encryption 1: CAR
>>>Encryption 2: SHIP

I have started by creating two lists: x = [] encryption_labels = [] this is where i am planning the Encryption 1, Encryption 2... and so on. To be formed.

but i am stuck :(

With just one list, you can iterate through the list using enumerate() to get both the index and the value. Then you can print stuff out depending on that:

x = ['CAR', 'SHIP']

for idx, val in enumerate(x):
    print(f">>>Encryption {idx + 1}: {val}")

which prints the following:

>>>Encryption 1: CAR
>>>Encryption 2: SHIP

I have an empty list which is continuously being appended when data is inputted via the input function e.g. x = [] After the first input, the list. Thank you for the good tips. I take it that this post an example of “Do as I say, not as I do.” (See list item #1.) Elke on January 04, 2011 11:09 am. Thanks for the tips for formatting list. I’d prefered to find some examples going with every tip, so I could better imagine how the list might look when keeping to the tip. Regards, Elke

Just iterate through and access the respective index

for i in range(len(x)):
  print(encryption_labels[i] + ": " + x[i])

Python List append(), The elements of a list don't have to be the same type. append is a list method which adds the argument passed to it to the end of the list. But this always had to be accompanied by legal small-print warning the reader that "a", "crook"] print("Test 1: {0}".format(this is that)) that = this print("Test 2: {0}".format(this is that ))� See the guide and sample code for specific details of how tables are detected and data is appended. The caller must specify the spreadsheet ID, range, and a valueInputOption . The valueInputOption only controls how the input data will be added to the sheet (column-wise or row-wise), it does not influence what cell the data starts being written to.

You can convert x to encryption_labels at the end after finishing appending all the elements to x:

encryption_labels = [f">>>Encryption {i+1}: {xi}" for i, xi in enumerate(x)]

All data structures in q are ultimately built from lists: a dictionary is a pair of lists; a table is a special dictionary; a keyed table is a pair of tables. Thus it is important to have a thorough grounding in lists. All lists are equal but some lists are more equal than others.

  • What's the purpose of this formatting? If you just wish to print the list like that you can create a method that formats a string like that or do you need the values in the list to be prepended with "Encryption x:"
