How do I add comma to numbers and align those by the decimal points-CodePudding

I was able to align the numbers by decimal points but I don't know how to add the comma. I know how to add commas using the format() but don't know how to align and add commas together. I need to align by the decimal points and have commas also.

print(f"{i   1}\t\t\t{salary :11.2f}")

This is a line inside the for loop.

This worked for me, if I understood you correctly. Replace the 3 tabs you have with ">25", directly after the colon. The ">" adds space to the left and the text will be aligned to the right. 25 is how many character spaces you're allowing for. 25 was an arbitrary number I picked for this example, it can be anything with enough space to fit your strings and the space desired (like, the longest numbers you have plus your tab spaces). Add the comma after ">25" to print the numbers with commas.

salaries = [10000, 200000, 3000000, 40000000]

for i in range(len(salaries)):
    salary = salaries[i]
    print_string = f"{i   1}{salary :>25,.2f}"
    print(print_string)

Below solution requires administrative permissions.

Step 1: Install German locale.

1.1 Uncomment German locale line in /etc/locale.gen.

Any text editor can be used. After editing result should look as follows:

grep ^de /etc/locale.gen
de_DE.UTF-8 UTF-8

1.2 Install German locale:

sudo locale-gen en_US.UTF-8 de_DE.UTF-8
sudo update-locale LANG=en_US.UTF-8 LC_ALL=en_US.UTF-8

Step 2. Use German locale. Example:

#!/usr/bin/python3.9
import locale
locale.setlocale(locale.LC_ALL, 'de_DE.UTF-8') 
for i in range(0,10):
    salary=10000*i 1000
    print('{0:2d}\t\t\t'.format(i 1),end='')
    print(locale.format_string('.2f', salary))

Output:

 1                          1000,00
 2                         11000,00
 3                         21000,00
 4                         31000,00
 5                         41000,00
 6                         51000,00
 7                         61000,00
 8                         71000,00
 9                         81000,00
10                         91000,00
