Question

我想将列表列表传输/写入txt文件。列表中的某些字符串包含引号，也应该转移。

但是如果我尝试在txt文件中编写它们，它们在字符串之前和之后包含三个引号。如何在不手动操作的情况下将"""3"""更改为"3"并将"""A1"""更改为"A1"？（列表列表包含65.000个列表...）没有引号的数字应该保持不变。

import csv

results = ['"3"', '"300.096"', '"0.033"', '45.4715', '35.903', '1', '0.205328', '0.0702029201671833', '"0"', '"A1"', '"STAR-"'],['"3"', '"300.096"', '"0.033"', '45.4715', '35.903', '1', '0.205328', '0.0702029201671833', '"0"', '"A1"', '"STAR-"']

path = "C:\\Users\\kaza\\Desktop\\Bla.txt"
with open(path, "w") as output:
    writer = csv.writer(output, lineterminator='\n')
    writer.writerows(A)

我得到的结果看起来像这样

"""3""","""300.096""","""0.033""",45.4715,35.903,1,0.205328,0.0702029201671833,"""0""","""A1""","""STAR-"""
"""3""","""300.096""","""0.033""",45.4715,35.903,1,0.205328,0.0702029201671833,"""0""","""A1""","""STAR-"""`

您正在使用引号编写数据。默认情况下，csv.writer()已使用引号字符来围绕可能在值中包含分隔符的数据，并将使用double {{1}转义值中的任何"个字符在用自己的""引号围绕值之前标记。

要么不在引号中包含引号（并引用".."类），要么禁用引号转义。

通过将quoting设置为csv.QUOTE_NONE并将quotechar值设置为csv.writer()，可以停用引用转义功能：

None

演示：

writer = csv.writer(output, lineterminator='\n', quoting=csv.QUOTE_NONE, quotechar=None)

当您设置>>> import csv >>> output = BytesIO() >>> writer = csv.writer(output, lineterminator='\n', quoting=csv.QUOTE_NONE, quotechar=None) >>> results = ['"3"', '"300.096"', '"0.033"', '45.4715', '35.903', '1', '0.205328', '0.0702029201671833', '"0"', '"A1"', '"STAR-"'],['"3"', '"300.096"', '"0.033"', '45.4715', '35.903', '1', '0.205328', '0.0702029201671833', '"0"', '"A1"', '"STAR-"'] >>> writer.writerow(results[0]) 84L >>> writer.writerow(results[1]) 84L >>> print(output.getvalue()) "3","300.096","0.033",45.4715,35.903,1,0.205328,0.0702029201671833,"0","A1","STAR-" "3","300.096","0.033",45.4715,35.903,1,0.205328,0.0702029201671833,"0","A1","STAR-"时，您可能希望为escapechar指定一个值，以便可以正确处理值中分隔符或行终止符的任何外观。

三个引号而不是一个
