如何按字符串而不是按字符拆分列表中的值？

Question

I have read in a text file and split the rows up into two separate lists. I'm trying to convert each of these two lists into a csv but I am running into a bit of a problem.

My current python code (using python 3) to do the writing to csv looks like this:

with open(bad_csv_file, 'w') as myfile:
      wr = csv.writer(myfile)
      for item in bad_csv:
        wr.writerow(item)
      myfile.close()

The rows I'm trying to write to csv look like this:

0000002 1 1E-10 1851 7 5 12 1851               
0000002 0 -97.6 22.2 -9999 -9999 0 0 97687 101325 45728 41.2 1e+05 1 0 0 0 0 0 -9999 -9999 -9999 -9999
0000003 1 1E-10 1851 7 10 12 1851               
0000003 0 -60 12 -9999 -9999 0 0 99993 101325 55402 25.7 1e+05 1 0 0 0 0 0 -9999 -9999 -9999 -9999
0000004 50 1E-10 1851 8 16 0 1851   

My current output looks like:

2,0,1,0,1,0,0,2, ,1,5,8, ,1, ,1,5,8, ,1,4,1,6, ,0, ,0, ,0, ,0, ,0, ,0, ,0, ,0, ,0, ,0, ,0, ,0, ,0, ,0, ,0, , , ,"
"
0,0,0,0,0,0,1, ,1,4, ,1,E,-,1,0, ,1,8,5,1, ,6, ,2,5, ,0, ,1,8,5,1, , , , , , , , , , , , , , , ,"
"
0,0,0,0,0,0,2, ,1, ,1,E,-,1,0, ,1,8,5,1, ,7, ,5, ,1,2, ,1,8,5,1, , , , , , , , , , , , , , , ,"
"
0,0,0,0,0,0,2, ,0, ,-,9,7,.,6, ,2,2,.,2, ,-,9,9,9,9, ,-,9,9,9,9, ,0, ,0, ,9,7,6,8,7, ,1,0,1,3,2,5, ,4,5,7,2,8, ,4,1,.,2, ,1,e,+,0,5, ,1, ,0, ,0, ,0, ,0, ,0, ,-,9,9,9,9, ,-,9,9,9,9, ,-,9,9,9,9, ,-,9,9,9,9,"
"
0,0,0,0,0,0,3, ,1, ,1,E,-,1,0, ,1,8,5,1, ,7, ,1,0, ,1,2, ,1,8,5,1, , , , , , , , , , , , , , , ,"

It seems to be splitting by character as opposed to the entire string of the number. Any help would be greatly appreciated, thanks!

Answer 1

Firstly, in your code you iterate over bad_csv which is unbound as far as the reader knows. The naming could be somewhat more clear to make us understand what you mean to do.

Secondly, if you iterate over a string it'll do it char by char . A row in the csvwriter is a sequence of strings or numbers . It'll iterate over that. What you need to do is to split your string on spaces . row = line.split(' ') Then row will be a sequence of your values. If you want to remove the spaces in the end use row = line.rstrip().split(' ')

Oh and you don't need to close a file if you opened it with with .
