what's a better why to iterate through this list of item and save it

if cursor:
    for row in cursor:
        date = str(row[0])
        servicelevel = str(row[1])
        power = str(row[2])
        rebootime = str(row[3])
        result = str(row[4])
        result_two = str(row[5])
        moredata = str(row[6])
        data_Rows.append({'date': date, 'servicelevel': servicelevel, 'power': power, 'rebootime': rebootime,
                           'result': result, 'result_two': result_two, 'moredata': moredata})

You could use a dictionary of field names to row indexes. For example:

cursor = [(1, 2, 3), (4, 5, 6)]
fields = { 'date' : 0 , 'servicelevel' : 1, 'power' : 2 }

data_Rows = []
for row in cursor:
    data_Rows.append({ f : str(row[v]) for f, v in fields.items() })



[{'power': '3', 'servicelevel': '2', 'date': '1'}, {'power': '6', 'servicelevel': '5', 'date': '4'}]

How to iterate through Java List? Seven (7) ways to Iterate Through , So if the for loop creates x, how do I save each iteration to x(i)? eg. x0, x1, x2 etc. App Shah • 1 year ago. Hi Lee - try saving each iteration� How to iterate through Java List? This tutorial demonstrates the use of ArrayList, Iterator and a List. There are 7 ways you can iterate through List. Simple For loop; Enhanced For loop; Iterator; ListIterator; While loop; Iterable.forEach() util; Stream.forEach() util; Java Example: You need JDK 13 to run below program as point-5 above uses stream() util.

Perhaps this:

if cursor:
    for row in cursor:
        data_Rows.append({'date': str(row[0]), 'servicelevel': str(row[1]), 'power': str(row[2]), 'rebootime': str(row[3]),
                           'result': str(row[4]), 'result_two': str(row[5]), 'moredata': str(row[6])})

Iterate over a list in Python, In Python, list is a type of container in Data Structures, which is used to store multiple data at the same time. Unlike Sets, the list in Python are� 3. List Comprehension to iterate through a list in Python. Python List Comprehension is an indifferent way of generating a list of elements that possess a specific property or specification i.e. it can identify whether the input is a list, string, tuple, etc. Syntax: [expression/statement for item in input_list] Example:

You can zip the column headers with each row to create a dict for each row with the dict constructor:

headers = 'date', 'servicelevel', 'power', 'rebootime', 'result', 'result_two', 'moredata'
data_Rows.extend(dict(zip(headers, map(str, row))) for row in cursor)

Iteration over lists | AP CSP (article), How to use loops to iterate over lists of data in computer programs. In programming, we use lists to store sequences of related data. but it instead calculates the discounted price of each item (25% off) and adds that price to a new list:. In this post, we will see how to loop through a list with index in Python. 1. enumerate() function. The pythonic solution to loop through the index of a list is using the built-in function enumerate(). The function was introduced in Python 2.3 to specifically solve the loop counter problem. It can be used as following:

for row in cursor:
    d = {}
    for i, v in enumerate(['date', 'servicelevel', 'power', 'rebootime', 'result', 'result_two', 'moredata']):
        d[v] = str(row[i])

Ways to Iterate Through List in Python, In this tutorial, we'll go over how to iterate through list in Python. Python List is basically an ordered data structure which enables us to store and. 1. [ expression / statement for item in input_list]� When you write a Microsoft Visual Basic for Applications (VBA) macro, you may have to loop through a list of data on a worksheet. There are several methods for performing this task. The "More Information" section of this article contains information about the methods that you can use to search the following types of lists:

Looping Through a List — Java Review, You can use a for-each loop to loop through all items of a list, just like you do with an array. b) A list can store objects, but arrays can only store primitive types. I'm trying to loop through items of a checkbox list. If it's checked, I want to set a value. If not, I want to set another value. I was using the below, but it only gives me checked items: foreach (DataRowView myRow in clbIncludes.CheckedItems) { MarkVehicle(myRow); }

In this article we will discuss different ways to iterate over a list. Iterate over the list using for-in loop. Its easies solution to iterate over the list i.e.

In this tutorial, learn how to loop over Python list variable. Loop through list variable in Python and print each element one by one. You have to use Python for loop and looping over a list variable and print it in the output. The list variable is the variable whose values are comma separated. All the items are enclosed within the square brackets.

  • what does f and V stand for? also why is it backward? starting from power?
  • @DavidShapero f, v in fields.items() successively assigns the keys and values from fields into those variables, so in the first iteration f = 'date', v = 0, then in the second f = 'servicelevel', v = 1 etc. I've used f and v as shorthand for field name and row value index
  • Thank you, if let's say I want to access date afterward what should I do?> data_Rows.get("date") or data_Rows["date"] ?
