将python dict数据写入CSV文件

Question

我正在使用以下代码将python dict写入CSV文件。

my_dict['date'] = time.strftime('%d-%m-%Y')
my_dict['error_log'] =  data
file_exists = os.path.isfile('build_error_deatils.csv')
with open('build_error_deatils.csv', 'a+') as f:
w = csv.DictWriter(f, my_dict.keys())
   if not file_exists:
       w.writeheader()
w.writerow(my_dict)

除了一大块日志数据之外，所有内容都要正确复制，如下面的字符串。

 data = """
../../../../../../../src/junos/usr.sbin/l2cpd/os/l2cpd_rts_reader.c: In function 'l2cpd_vpls_iff_get_stp_index':
../../../../../../../src/junos/usr.sbin/l2cpd/os/l2cpd_rts_reader.c:129: error: 'RTM_IFF_RLT_ACTIVE_LINK' undeclared (first use in this function)
../../../../../../../src/junos/usr.sbin/l2cpd/os/l2cpd_rts_reader.c:129: error: (Each undeclared identifier is reported only once
../../../../../../../src/junos/usr.sbin/l2cpd/os/l2cpd_rts_reader.c:129: error: for each function it appears in.)
cc1: warnings being treated as errors
../../../../../../../src/junos/usr.sbin/l2cpd/os/l2cpd_rts_reader.c:129: warning: unused variable 'addi'
make[1]: *** [l2cpd_rts_reader.o] Error 1
***

"""
 my_dict['error_log'] =  data

我得到的数据如下。

不确定为什么错误日志会变为空。 在这里需要帮助，而不是提前...

最后能够通过将字符串更改为原始字符串来解决此问题。

my_dict['error_log'] = repr(data)
