Python Power未发布：

 import csv,sys filename = 'a.csv' with open(filename,'rb') as csvfile: reader = csv.reader(csvfile,delimiter=',') try: for row in reader: if row[1].find(',') == -1: line = ','.join(row) print line else: for i in range(0,row[1].count(',')+1): line = row[0]+','+row[1].split(',')[i]+','+row[2].split(',')[i] print line except csv.Error as e: sys.exit('file %s, line %d: %s' % (filename, reader.line_num, e)) 

Answer 2

我认为您的文件不是真正的csv文件。 但你可以尝试这些代码，我认为它有效。

 def convert(strs): array=[] if len(strs)==4: array.append({ 'left':strs[0], 'right':strs[2] }) array.append({ 'left':strs[1], 'right':strs[3] }) else: array.append({ 'left':strs[0], 'right':strs[1] }) return array file='/Users/lidl/example.csv' sumarray=[] for line in open(file): line=",".join(line.split())# rebuild a str line with comma segmentation strs=line.split(",") sumarray=sumarray+convert(strs) for item in sumarray: print(item['left']+" "+item['right']) 

对不起代码格式不好。

Answer 3

这是一个快速的Ruby版本：

 #!/usr/bin/ruby # header puts STDIN.gets while line = STDIN.gets left, right = line.split left = left.split(',') right = right.split(',') left.each_with_index{ |item, i| break unless right[i] puts item + "\t" + right[i] } end
