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 ...
In these examples, the ".4f" specifier formats the input value as a floating-point number with four decimal places. With the ",.2f" format specifier, you can format a number using commas as thousand separators and with two decimal places, which could be appropriate for formatting currency va...

The numbers 5.0, 2.5, and -3.4 are examples of floating point numbers. Floating point numbers may be equivalent to integers. For example, 5.0 is equal to 5 in Python: 5.0 == 5 returns True. Arithmetic with floating point numbers is often very slightly imprecise, just as it is in many ...

1)花括号({})是一个占位符,表示这里将要传入print语句一个具体的值,这里就是变量z的值。 2)0指向format()方法中的第一参数,在这里,只包含一个参数z,所以0就指向这个值;相反,如果有多个参数,0就确定的表示传入第一参数。 3)冒号(:)用来分隔传入的值和它的格式。
