所以基本上我試圖爲python應用程序創建基於文本的用戶界面。這是我走到這一步:只清除Python中的部分屏幕
#!/usr/bin/env python
# encoding: utf-8
from blessed import Terminal
import sqlite3
import sys
import os
reload(sys)
sys.setdefaultencoding("UTF-8")
db = sqlite3.connect('/Users/JoaoPedro/Desktop/PyTest/Alunos')
c = db.cursor()
term = Terminal()
os.system('clear')
def main (self):
print (term.yellow(" CICS 000009/1 Centro Educacional Charles Darwin z\OS 3.2 "))
print (term.yellow(" TERMINAL: 2297 Sistema de Controle de Notas VITÓRIA/ES "))
print (term.yellow(" ======================================================================================= "))
print (term.move_y(28)) + (term.yellow(" ======================================================================================= "))
matricula = raw_input (term.move(4, 7) + "Matrícula: ")
os.system('clear')
print (term.yellow(" CICS 000009/1 Centro Educacional Charles Darwin z\OS 3.2 "))
print (term.yellow(" TERMINAL: 2297 Sistema de Controle de Notas VITÓRIA/ES "))
print (term.yellow(" ======================================================================================= "))
print
print (term.cyan(" Matrícula Nome Série Turma Nota "))
if matricula in ["/", ""]:
c.execute('select * from A ORDER BY nome')
rows = c.fetchall()
else:
c.execute('select * from A WHERE matricula = ?', (matricula,))
rows = c.fetchall()
for row in rows:
print (term.white((term.move_x(9)) + row[0] + (term.move_x(20)) + row[1] + (term.move_x(56)) + row[2] + (term.move_x(64)) + row[3] + (term.move_x(73)) + row[4]))
print (term.move_y(28)) + (term.yellow(" ======================================================================================= "))
command = raw_input (term.move(27, 2) + "Comando ===> ")
if command == "X":
os.system('clear')
sys.exit()
else:
os.system('clear')
main('self')
main('self')
正如你所看到的,我有打印的頂部,每一個新的查詢發生時的底部。現在,這對於像這樣的小應用程序來說工作得很好,但是如果我添加更多功能,每次都必須重複同一行代碼(頂部和底部)。
我想知道是否有任何方法來保持頂部和底部的靜態,只允許程序清除之間的區域......?
哇更換三個打印線的每次出現!這其實很不錯,我從來沒有想過這個笑話 –
