在tushare中埋泵，任何數(shù)據(jù)處理的前提都是獲取最新的股票代碼列表磺送，有兩種方式可以獲得：
方法一
使用ts.get_today_all()
返回結(jié)果如下：
,code,name,changepercent,trade,open,high,low,settlement,volume,turnoverratio,amount,per,pb,mktcap,nmc

改方法的缺點(diǎn)是獲取數(shù)據(jù)的速度比較慢躯泰，實(shí)測(cè)大約10-15秒左右栈戳，根據(jù)用戶的網(wǎng)絡(luò)情況而定厨剪。
方法二
使用ts.get_stock_basics()
耗時(shí)約1-2秒
返回結(jié)果如下：
code,name,industry,area,pe,outstanding,totals,totalAssets,liquidAssets,fixedAssets,reserved,reservedPerShare,esp,bvps,pb,timeToMarket,undp,perundp,rev,profit,gpr,npr,holders

結(jié)論
1.兩種方法對(duì)于系統(tǒng)的開(kāi)銷不同哄酝，視使用場(chǎng)景和需獲取的數(shù)據(jù)類型決定使用何種方法。
2.兩種方法均只能獲取傳統(tǒng)型的股票代碼祷膳，比如600陶衅、000、300等開(kāi)頭的代碼直晨，不支持510搀军、1599開(kāi)頭的ETF基金
3.對(duì)于ETF，我一般將經(jīng)常需要處理的代碼匯總成list抡秆，直接導(dǎo)入系統(tǒng)查詢奕巍，列表如下：['512880','510050','510180','510230','510300','510500','510880','510900','159901','159902','159915','159919','159920','159934','159937','159938','159949','159952']
特別提示：一個(gè)小坑
在list導(dǎo)入時(shí)，python會(huì)將代碼認(rèn)定為int類型儒士，所以在查詢諸如000555的代碼時(shí)的止，會(huì)變成ts.get_k_data(555)，從而會(huì)報(bào)錯(cuò)着撩，因此list處理時(shí)诅福，需要補(bǔ)0。此處需要使用int型數(shù)據(jù)補(bǔ)零方法
#int型數(shù)據(jù)補(bǔ)零方法
i = "%06d" % i
#文本型數(shù)據(jù)補(bǔ)零方法
i=i.zfill(6)
運(yùn)行代碼
