Processes and Threads

Clarification:the resources associated with a process include memory pages (all the threads in a process has the same VI EW of the memory), file descriptor

Introduction to the understanding of rawstring in Python _python

. Example: >>> print (R ' C:\Windows\System32 ') C:\Windows\System32 >>> print (' C:\\Windows\\System32 ') C:\Windows\System32 >>> print (' C:\Windows\System32 ' ) C:\Windows\System32 >>> The last line can also be effective because \w and \s are nothing. So in this example python finds "cannot escape", so it does not do any escaping and directly prints the escape character. But: >>> print (' C:\Windows\System32\new ') C:\Windows\System32
