前段時間小編在刷抖音的時候看到很多人用bat制作黑客帝國的數字雨，比如：

bat代碼

@echo off title 黑客帝國 setlocal ENABLEDELAYEDEXPANSION color 0a for /l %%i in (1,1,80) do ( set Down%%i=0 ) :loop for /l %%j in (1,1,80) do ( set /a Down%%j-=1 if !down%%j! LSS 0 ( set /a Arrow%%j=!random!%%4 set /a Down%%j=!random!%%15+10 ) if "!Arrow%%j!" == "1" ( set /a chr=!random!%%2 set /p=!chr!<nul ) else ( set /p= <nul ) ) goto loop goto :eof

那么如何用Python制作黑客帝國的代碼雨呢？

安裝

采用Python包管理工具pip安裝即可：

pip install git+https://github.com/will8211/unimatrix.git
運行

安裝好以后在終端運行下面命令即可：

unimatrix -n -s 96 -l o unimatrix -c blue -u ILovePython unimatrix -c yellow -l e

Lines will move at varied speeds.-b Use only bold characters-c COLOR One of: green (default), red, blue, white, yellow, cyan,magenta, black-f Enable "flashers," characters that continuously change.-g COLOR Background color (See -c). Defaults to keepingterminal's current background.-h Show this help message and exit-l CHARACTER_LIST Select character set(s) using a string over lettercodes (see CHARACTER SETS below.)-n Do not use bold characters (overrides -b)-o Disable on-screen status-s SPEED Integer up to 100. 0 uses a one-second delay beforerefreshing, 100 uses none. Use negative numbers foreven lower speeds. Default=85-t TIME Exit the process after TIME seconds-u CUSTOM_CHARACTERS Your own string of characters to display. Enclose insingle quotes ('') to escape special characters. Forexample: -u '#$('-w Single-wave mode: Does a single burst of green rain,exits.

Use the sameletter multiple times to increase the frequency of the character set. Forexample, the default setting is equal to '-l knnssss'.* With most modern Linux terminals (gnome-terminal, konsole, lxterminal,xfce4-terminal, mate-terminal) simply having the font installed system-wideis enough. The terminal will fall back to it for the Klingon, meaning thatyou don't have to select it in your terminal settings. 'Horta' seems not towork in Konsole. Fonts may need to be set manually as fallbacks in.Xresources for older terminals, such as urxvt and xterm.KEYBOARD CONTROLSPACE, CTRL-c or q exit- or LEFT decrease speed by 1+ or RIGHT increase speed by 1[ or DOWN decrease speed by 10] or UP increase speed by 10a toggle asynchronous scrollingb cycle through bold character options(bold off-->bold on-->all bold)f toggle flashing characterso toggle on-screen status1 to 9 set color: (1) Green (2) Red (3) Blue (4) White(5) Yellow (6) Cyan (7) Magenta (8) Black(9) Terminal default! to ( set background color (same colors as above, but pressingshift + number)EXAMPLESMimic default output of cmatrix (no unicode characters, works in TTY):$ unimatrix -n -s 96 -l oUse the letters from the name of your favorite operating system in bold blue:$ unimatrix -B -u Linux -c blueUse default character set, plus dollar symbol (note single quotes aroundspecial character):$ unimatrix -l knnssssu -u '$'No bold characters, slowly, using emojis, numbers and a few symbols:$ unimatrix -n -l ens -s 50
