Python formatted output print

1. Commonly used format symbols

% Symbol Usage List:

Format symbols	Transformation
%d	Signed decimal integer
%i	Signed decimal integer, and automatically converts the octal (or hexadecimal) input into decimal
%u	unsigned decimal integers
%c	Characters and their ASCII code
%s	String, formatted by a string conversion of STR ()
%o	unsigned integer (octal)
%x	unsigned integer (hexadecimal)
%x	unsigned integer (16 uppercase characters)
%e	Floating-point numbers (scientific notation), lowercase E
%E	Floating-point numbers (scientific notation, E instead of e)
%f	Floating point number (with decimal point symbol)
%g	Floating-point numbers (%e or%f depending on the size of the value)
%G	Floating-point numbers (similar to%g)
%p	Pointer (memory address of the value printed in hexadecimal)
%n	Stores the number of output characters into the next variable in the parameter list
%%	Percent Sign

2. Format () Formatting indicator Description

' B '-binary. The number is output as a base of 2. ' C '-character. Converts an integer to the corresponding Unicode string before printing. ' d '-decimal integer. The number is output as a base of 10. ' o '-eight binary. The number is output as a base of 8. ' x '-16 binary. The number is output in 16, and the number of digits above 9 is in lowercase letters. The ' e '-power symbol. Print numbers in scientific notation. Use ' e ' to indicate power. ' G '-general format. The value is output in fixed-point format. When the number is particularly large, it is printed in a power form. ' n '-number. When the value is an integer and ' d ', the values are the same as the ' G ' when they are floating-point numbers. The difference is that it inserts a numeric delimiter according to the locale. '% '-percent. Multiply the value by 100 and then print in fixed-point (' F ') format, followed by a percent semicolon.

3. Specify the alignment of the string for the desired length:

< (default) align Left> Right Alignment^ Middle Alignment= (for numbers only) after the decimal point 4. Python_ Escape Character

Escape character	Describe
\ (at end of line)	Line continuation character
\\	Backslash symbol
\‘	Single quotation marks
\"	Double quotes
\a	Bell
\b	BACKSPACE (Backspace)
\e	Escape
\000	Empty
\ n	Line break
\v	Portrait tab
\ t	Horizontal tab
\ r	Enter
\f	Page change
\oyy	Octal number yy represents the character, for example: \o12 represents a newline
\xyy	The decimal number yy represents the character, for example: \x0a represents a newline
\other	Other characters are output in normal format
