[Python] Numpy - for Data Analysis

1. open a csv file
   - np.loadtxt

2. data preparation
   - answer1=score[:,10:]
   - rset1=score[:, :10]
   - tmp=np.ones(22, dtype='uint8')
   - tmp=tmp*4
   - tmp[20:]=1
   - bool_answer1=(answer1==rset1)
   - scoreset=bool_answer1*1
   - scoreset[20:]=rset1[20:]

3. data integration
  - np.dot

4. show charts using datas
   - plt.plot
   - plt.bar
