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 =...
A number of types support format strings, including all numeric types (both standard and custom format strings), all dates and times (both standard and custom format strings) and time intervals (both standard and custom format strings), all enumeration types enumeration types, and GUIDs https:/...
Perform a string formatting operation. The format_string argument can contain literal text or replacement fields delimited by braces {}. Each replacement field contains either the numeric index of a positional argument, or the name of a keyword argument. Returns a copy of format_string where each...
The<flag causes the argument for the previous format specifier to be reused. All three specifiers refer to thecvariable. ThetYconversion characters give a year formatted as at least four digits with leading zeros as necessary,tmgive a month, formatted as two digits with leading zeros as necessa...
In this case, the 3d format specifier tells Python to display the grade using up to three characters. A leading space is used if the grade doesn’t have three digits. Line 13 adds the comment part. Lines 16 to 21 build the final report and return it to the caller. Now that you’ve...
the precision may be optionally specified as a format modifier - using a precision of 0 suppresses the radix character; the exponent is always printed in at least 2 digits, and can take up to 3 for example, 1e+01, 1e+10, and 1e+100 'f' fixed decimal notation of the form [-]<d...

If the magnitude is zero, it is represented by a single zero character'0'('\u005Cu0030'); otherwise, the first character of the representation of the magnitude will not be the zero character. The behavior of radixes and the characters used as digits are the same as#toString(int, int)...
