python – How can I print items with no value?

I am currently using a cvs file and I’ve been trying to figure out how can I print out items without calories so my output should look like this
example..

Beef , 190
Eel, 300

what i have inside the csv is

Item, Carbs, Calories

But what i want is
Item, Calories

I just want to print the items that has the value of 0 in carbs.

This is my code

import csv

def read_csv (filename): #function to read csv
    items = () #store the item
    carbs = () #store the carbs
    calories = () #store the calories
no_carbs = () #store null carbs item
    for i in range(0, len(carbs)): 
        if int(carbs(i)) == 0:
            no_carbs.append((items(i),calories(i)))

    no_carbs = sorted(no_carbs) #sort items on the basis of item name
    for i in no_carbs: 
       print(f'{i(0)} {i(1):.0f}')

read_csv("food.csv") #call function to read file

Can Someone please help me and explain to me what should i use and do?

debugging – Style function not working inside Print Row functions

About

Watch(...) is a helper function for watching a list of variables or other functions inside a Module(...) during programming or troubleshooting.

Goal
Style Row(...) separator so that printed values print apart with distinctively styled separator between items.

Two Coding Attempts

For first attempt (watch1(...)) separator works but does not style separator. For second attempt (watch2(...)) separator is itself styled but kernel complains by reacting with error codes and nothing else works.

list = {a, b, c};

Separator = ToString(Style(" | ", Darker(Green), Bold, 12));
watch1(list_) := 
  Print(Row(
    Table(ToString(list((i))) <> Separator, {i, Length(list)})));
watch1(list)

watch2(list_) := 
  Print(Row(
    Table(ToString(list((i))) <> 
      Style(" | ", Darker(Green), Bold, 12), {i, Length(list)})));
watch2(list)

Specific Request

Please help by correcting code so that it works as cited in Goal.

python – Python3 Print on the same line – Numbers in 7-segment device format

I am new to Python and am having difficulty printing the output on one line.

This belongs to the Python Learning Python Essentials Lab 5.1.10.6 online class and printing on a 7-segment device. If you are not familiar with a 7-segment device, check Wikipedia.

I am NOT using any external device. I only need it to print on my own terminal. All the other StackOverflow solutions I found are related to the use of real devices and did not help.

  • Laboratory link:
    https://edube.org/learn/programming-essentials-in-python-part-2/lab-a-led-display

  • Purpose: Request the user the number; print number on 7-segment display
    format your terminal.

  • Notes: Using Python 3.9. I tried 3 alternative solutions (Option 1,2,3), but none does what I want.
  • INSTRUCTIONS: Des / Comment Option 1,2, or 3 to execute only that option
  • I found this workaround, which I mainly understand and accomplish what I am trying to achieve. However, it's a totally different approach and I wouldn't have thought of it. I know there are many ways to strip a 7-segment device, and if this is the most correct one, I will learn it. But I feel like I'm so close and I'm just superfluous 'n' Far from solving it with my own method and I'm just trying to understand what I'm missing.

Thanks for your help.

Is there a way to change the print dialog in Google Sheets to the last default selection OR to "selected cells"

I hardly ever want to print a complete worksheet. Usually I want to print a block of 15 rows by 8 columns.

Every #$ & ^ $ time I have to change from "print entire sheet" to "print selected cells" Is there a way to make this change permanent so the DEFAULT is to print the selected cells?

Interestingly, the print dialog box remembers the centering of the previous print.

(To anticipate comments: Yes, I have mentioned it in the comment sheets. Several times.)

How do I print a 3 * 3 matrix with recursion?

without using cycles like For, etc.

printing: printer does not print after reinstalling ubuntu 20.04 Part A

First, be patient with me since I'm new to ubuntu. I had Ubuntu 19.10 installed on my computer and my printer didn't work. I upgraded to 20.04 and still had no problems until I had to reinstall 20.04. In the first install startup directory it was all one, now I have switched to startup on a separate partition (I don't think that's part of the problem, but & # 39; I'm trying to give you as much info as I can I went into ubuntu wiki "debugging print issues" and ran the terminal commands that were there, below is the output of my terminal session.
