实验五

实验任务3： 
 1 with open('data3.txt','r',encoding='utf-8')as f:
 2     t=f.readlines()
 3     p=[]
 4     for i in t:
 5         if t[0]==i:
 6             y='原始数据'+'\t'+'四舍五入后数据'+'\n'
 7             p.append(y)
 8         else:
 9             y=i.strip('\n')+'\t'+str(round(eval(i)))+'\n'
10             p.append(y)
11 with open('data_process.txt','w',encoding='utf-8')as f:
12     x=''.join(p)
13     f.write(x)
14 with open('data_process.txt','r',encoding='utf-8')as f:
15     t=f.readlines()
16     a=[]
17     b=[]
18     for i in t:
19         if t[0]!=i:
20             y=i.strip('\n')
21             z=y.split('\t')
22             a.append(eval(z[0]))
23             b.append(eval(z[1]))
24 print('原始数据:','\n',a)
25 print('四舍五入后数据:','\n',b)

实验任务4：

 1 with open('data4.txt', 'r+', encoding='utf-8') as f:
 2     str = [j.strip('\n').split('\t') for j in f]
 3     a = str.pop(0)
 4     str.sort(key=lambda x: (x[2], -int(x[-1])))
 5     print('\t'.join(a))
 6     for i in str:
 7         print('\t'.join(i))
 8 with open('data4_progressed.txt', 'w') as f:
 9     f.write('\t'.join(a))
10     f.write('\n')
11     for i in str:
12         f.write('\t'.join(i))
13         f.write('\n')

实验任务5：

 1 with open('data5.txt','r',encoding='utf-8')as f:
 2     text1=f.read()
 3 l=text1.splitlines()
 4 print('行数：'+str(len(l)))
 5 print('单词数：'+str(len(text1.split())))
 6 print('空格数：'+str(text1.count(' ')))
 7 print('字符数：'+str(len(text1)))
 8 with open('data5_with_line.txt','w',encoding='utf-8')as f:
 9     for i in range(len(l)):
10         f.write(str(i+1)+'  '+l[i]+'\n')

不会啊不会写
