用于读取和创建riscure检查器跟踪集文件（.trs）的库
trsfile的Python项目详细描述
python中的inspector跟踪集.trs文件支持
riscure检查器使用.trs文件格式保存和读取磁盘上的跟踪。为了更好地帮助从第三方读取和写入跟踪集文件，riscure发布了这个python库。
快速启动
该库支持读取和写入^ {CD1>}文件，但它不支持（^ {EM1}$/EME>）支持修改现有的{{CD1>}文件。TraceSet和Trace类都模拟了list的所有功能，所以切分您的心意吧！
安装
此库在PyPi上可用于python 3及更高版本。只需将trsfile添加到requirements.txt或通过命令行安装即可：
pip install trsfile
正在读取.trs文件

创建.trs文件

将TraceSet从一种类型转换为另一种类型
importrandom,os,trsfilewith \ trsfile.open('trace-set',# Previously create trace set'r',# Read only modeengine='FileEngine'# Using the FileEngine)astraces, \ trsfile.open(# Note: TrsEngine is the default'trace-set.trs',# Name of the new trace set'w',# Write modeheaders=traces.get_headers()# Copy the headers)asnew_traces:new_traces.extend(traces)# Extend the new trace set with the# traces from the old trace set
