Python Learning-terminal font highlighting 1

1, using the native escape character sequence, the version of Windows does not support (such as Win7), the perfect support for Linux

Implementation process:

The character color of terminal is controlled by escape sequence, and it is the system display function in text mode, which is independent of the specific language.

The escape sequence begins with the ESC, which is done with \033 (the ASCII code for ESC is 27 in decimal notation, or 033 in octal).

Format:

opening Section :\033[display mode, foreground color, background colour m + End part:\033[0m

Note: the first part of the three parameters: Display mode, foreground color, background color is an optional parameter, you can write only one of them, in addition, because the three parameters of the different meaning of the values are unique and no duplication, so the three parameters of the writing sequence is not fixed requirements, the system can identify However, it is recommended that you write in the default format specification. for the end part, can also be omitted, but in order to write the specification, it is suggested \033[*** beginning, \033[0m end. With this native escape sequence output, fully supported under Linux, but there is a compatibility problem under Windows, such as the normal display of color under WIN10, under Win7 does not support. Therefore, you can use the Python standard library to provide the Colorama module output color font, this module is cross-platform, the internal implementation is also the escape sequence to display color, but the Windows platform to do special processing, so fully compatible with Linux and Windows versions. the meaning of the numeric parameter representation: Description:

Front view	Background color	Color
30	40	Black
31	41	Red
32	42	Green
33	43	Yellow
34	44	Blue
35	45	Purplish red
36	46	Cyan Blue
37	47	White

Display mode:

Display mode	Significance
0	Terminal default settings
1	Highlight Display
4	Use underline
5	Flashing
7	Anti-white display
8	Not visible

Output Result:

2. Use the Python standard library Colorama module-compatible with Linux and Windows editions:

Output Result: 3 , using Python's Termcolor module:
