问题描述
在转储/序列化输入中具有长行的数据时,pyyaml 会在新行中添加额外的缩进 - 这很烦人,我们如何避免在两行/多行中进行这种转换?
While dumping/serializing data having long lines in input, pyyaml adds extra indentation with new line - which is annoying, how can we avoid this conversion in two lines / multiple lines ?
例如
在 [1] 中:
x = "-c /home/user/test/test2/test23/tet/2s/test1/stest/longdirectory1/directory2/ --optnion12 --verbose"
在[2]中:导入yaml
在 [3] 中:print (yaml.dump([dict(ATTRIBUTES=[dict(CONFIG=x)])], default_flow_style=False))
一个错误
- ATTRIBUTES: - CONFIG: -c /home/user/test/test2/test23/tet/2s/test1/stest/longdirectory1/directory2/ --optnion12 --verbose
应该是这样的
- ATTRIBUTES: - CONFIG: -c /home/user/test/test2/test23/tet/2s/test1/stest/longdirectory1/directory2/ --optnion12 --verbose
推荐答案
感谢@MathieuMarques 建议查看@dump 选项和提供的链接,YAML 文档不够好,无法找到.
Thanks @MathieuMarques for suggesting to look @ dump options and link provided, YAML documentation was not good enough to find it out.
无论如何,解决方案是为 dump 函数指定 width 参数.
Anyways solution is to specify width parameter for dump function.
即yaml.dump(data, width=1000)
@RandomCoder 建议使用 yaml.dump(data, width=float("inf")) 永久解决方案.
A better approach suggested by @RandomCoder to use yaml.dump(data, width=float("inf")) for a permanent solution.
