To format numbers with commas in Python, you can use f-strings, which were introduced in Python 3.6. Simply embed the number within curly braces and use a colon followed by a comma, like this:formatted_number = f"{number:,}". This will format the number with commas as thousand separator...
When you write large numbers by hand, you typically group digits into groups of three separated by a comma or a decimal point. The number 1,000,000 is a lot easier to read than 1000000.In Python, you can’t use commas to group digits in integer literals, but you can use underscores ...
You can use an expression in the f-string to format the number with a comma as the thousands separator and optionally rounded to N decimals. main.py my_int = 489985123 # ✅ Format integer with commas as thousands separator result = f'{my_int:,}' print(result) # 👉️ 489,985,...
F-strings also support format specifiers that control numerical precision, alignment, and padding. Format specifiers are added after a colon (:) inside the curly brackets. For instance,f'{price:.3f}'ensures that the floating-point number stored inpriceis rounded to three decimal places: price =...
