Using f-strings to format a 6-digit number with commas, round it to 1 significant figure and avoid scientific notation?

Question

This is my code so far:

number = 201234
print(f'number is {number:,.0f}')

This prints: number is 201,234

However I want it to print: number is 200,000

I've tried using print(f'number is {number:,.1g}') but this prints in scientific notation like so: number is 2e+05

Is there a simple way to format this to get the desired outcome?

Why not just `f'{str(number)[0]}00,000'`? – Tomerikoo Oct 06 '20 at 14:43 — Tomerikoo, Oct 06 '20 at 14:43

Use the round() function with a negative argument.

number = 201234
print(f'number is {round(number, -5):,.0f}')

Prints

number is 200,000

This is not a duplicate question, I wanted to know if it's possible to do this with f-strings and without using round. – Michael Gomes Vieira Oct 07 '20 at 09:36
