SAS日常使用的语句预定的python表达

1

导入数据

Sas:

filenameexport"C:\Users\Desktop\test.csv"encoding='utf-8';

PROCIMPORTout=raw.xingye_appl

datafile= export

dbms= csvreplace;

RUN;

Python：

Tmp=pd.read_csv('C:\\Users\\Desktop\\test.csv',dtype=object)

2

导出数据

Sas :

PROCEXPORTDATA=test

OUTFILE=" C:\Users\Desktop\test.csv"

DBMS=csv

label

REPLACE;

RUN;

Python:

Tmp.to_csv('C:\Users\Desktop\test.csv',index=False,encoding="utf-8")

3

过滤数据之后保留列

Sas:

datatmp;

setdf;

wherea="y";

keepa b;

run;

python:

tmp1=df[df['a']!='y'][['a','b']]

4

删除变量

Sas:

datadf;

setdf;

dropa b;

run;

python:

df=df.drop(['a','b'],axis=1)

5

重命名

Sas:

datatmp;

settmp;

renameaa_1=aa bb_1=bb;

run;

python:

tmp=tmp.rename(columns={'aa_1':'aa','bb_1':'bb'})

6

排序

Sas:

procsortdata=tmp;byb;run;

python:

tmp=tmp.sort_values(by = ['b'],axis =,ascending = True)

7

表连接

Sas

procsortdata=tmp;byaa;quit;

procsortdata=tmp1;byaa;quit;

datatmp2;

mergetmp(in=a) tmp1(in=b);

byaa;

ifa;

quit;

datatmp2;

mergetmp(in=a) tmp1(in=b);

byaa;

ifa and b;

quit;

python:

pd.merge(tmp,tmp1,how='left',on='aa')

pd.merge(tmp,tmp1,how='inner',on='aa')

8

变量分段

Sas

data tmp;

settmp;

if2000thennew_aa='[0, 2000)';

elseif200010000thennew_aa='[2000, 10000)';

elseif1000020000thennew_aa='[10000, 20000)';

elseif20000100000thennew_aa='[20000, 100000)';

run;

python

aa=[,2000,10000,20000,100000]

tmp['new_aa'] = pd.cut(tmp['new'], aa,right=False)

9

追加表

Sas:

procappendbase=tmp1data=tmp2;run;

python:

tmp1=tmp1.append(tmp2)
