手邊方格紙剛好用完，要不自己做一個？

這項目的緣起只是因為早上忽然發現家中的方格紙沒了，外頭又再下大雨，閒閒沒事想說自己來尻一下順便練習 python 手感

項目目標

熟悉 Reportlab 的繪圖與 PDF 檔案匯出操作
熟悉物件導向，力求主程式簡單
熟悉項目資料夾架構
範例

使用語言

Python

我使用的工具

Sublime
Git
- Tower (Mac only)

學習需要能力/材料

強烈建議

家裡有印表機
有支持世大運
按這篇文章讚

有會更好

物件導向概念
基本 list 概念與操作方法
package 安裝方法
一點點程式邏輯拆解怎麼用一個 function 畫出主/副線框

How to use it?

Open the GitHub repository
Fork it
Clone it and create a copy on your computer
Modify the settings.py file
Run the main.py

How to learn it?

Check the tutorial of reportlab package first, get to know how to create a canvas, put something on it and export it to the pdf file
Check how does the grid function works
Start to build the basic main python file: create a canvas > generate the grid > export
Use list .append() and while loop function to create the xlist/ylist (pls check out myfunc.py/xylist)
Because u would like to add a major grid in the end, so pls make sure the total numbers of both columns and rows u create can be divided by 5, the hint is trying to use the for loop inside the while loop
Write a boolean variable into your fun, so that both major/minor grids can call it
Use xylist to draw a grid
Now u might find out the whole grid doesn't locate at the middle
Create the align() function to compute the right starting point, then pass the value to xylist[0]
Everything just done, but try to do more! Separate all the setting and canvas Spec from main.py

        self.colorMinor=pink #check the default setting below
        self.lineWidthMinor=1

        #Major line setting: if u dont want the major grid, set the majorLine=False
        self.majorLine=True
        self.colorMajor=pink #check the default setting below
        self.lineWidthMajor=2<div>
