我有一个固定宽度的文件，在导入和拆分为31个txt文件时没有问题。在此过程中，固定宽度文件中的空格得以保留，因为写入txt只是将固定宽度文件中的每个条目写为新行。
我的问题是，当我使用python的csv函数时，这些空格将替换为“（引号）作为占位符。
我正在查看是否有一种方法可以产生不带双引号的csv文件作为占位符，同时保持最初在固定宽度文件中设置的所需格式。
txt文档中的首行：

原因：
您面临的问题是，在row处理过的数据中有仅包含csv.delimiter字符的列表条目。然后，模块用引用来区分您的“仅分隔符数据” 和“列之间的分隔符” 。
当使用[ ["PAY","...."," "," "," "," "] ]作为分隔符将' '之类的内容写入csv时，将其输出引用：
导入csv
dict_of_record_lists = {"K": [ ["PAY","...."," "," "," "," "] ] }
for key, value in dict_of_record_lists.items():
write_loc = 't.txt'
with open(write_loc, "w", newline='') as csvfile:
writer = csv.writer(csvfile, delimiter=' ')
for i in value:
writer.writerow(i)
print( open(write_loc).read()) # PAY .... " " " " " " " "
修复：
您可以修复指定quoting=csv.QUOTE_NONE并提供escapechar = ...的问题，也可以修复数据。但是，提供一个escapechar会将其放入您的文件中。
文档的相关部分：csv.QUOTE_NONE。
您可以操纵数据以不仅包含定界符作为数据：
for key, value in dict_of_record_lists.items():
write_loc = 'c:/Users/location/E02_ingestion/'+ key +'_'+csv_ext
with open(write_loc, "w", newline='') as csvfile:
writer = csv.writer(csvfile, delimiter=' ')
for i in value:
# if an inner item only contains delimiter characters, set it to empty string
cleared = [x for x in i if i.strip(" ") else ""]
writer.writerow(cleared)

能够将初始文字书写部分更改为：
for key, value in dict_of_record_lists.items():
write_loc = 'c:/Users/Steve Barnard/Desktop/Git_Projects/E02_ingestion/'+ key +'_'+csv_ext
with open(write_loc, "w", newline='') as parsed_file:
for line in value:
line_pre = "%s" % line
parsed_file.write(line_pre[:-1]+'\n')
所有问题都通过避免使用python内置的CSV编写器来解决。 我的程序在行切片后添加逗号的方式，剩下一个逗号和'\ n'。这导致write函数中的[：-1] slice删除\ n而不是最后的'，'。通过在逗号去除后添加'\ n'，解决了整个问题，并创建了保留间隔的功能CSV。
可以通过在写入时换出扩展名来创建文本文件。
