簡(jiǎn)易畫圖工具(Python)，供大家參考，具體內(nèi)容如下

專注于為中小企業(yè)提供成都網(wǎng)站制作、網(wǎng)站建設(shè)、外貿(mào)網(wǎng)站建設(shè)服務(wù),電腦端+手機(jī)端+微信端的三站合一,更高效的管理,為中小企業(yè)東光免費(fèi)做網(wǎng)站提供優(yōu)質(zhì)的服務(wù)。我們立足成都，凝聚了一批互聯(lián)網(wǎng)行業(yè)人才，有力地推動(dòng)了上1000+企業(yè)的穩(wěn)健成長(zhǎng)，幫助中小企業(yè)通過網(wǎng)站建設(shè)實(shí)現(xiàn)規(guī)模擴(kuò)充和轉(zhuǎn)變。

小黑最近在努力的入門python，正好學(xué)習(xí)到了Python的tkinker模塊下的Canvas(畫布)和Button(按鈕)再加上相應(yīng)的事務(wù)管理，實(shí)現(xiàn)了一個(gè)簡(jiǎn)單的畫圖小工具。
