Explain the use of regular expressions in Python

If you read a file directly at the command line with input and raw_input, and want to take the file directly into the command line to handle it,

The input method can be processed directly, and if you want to use the Raw_input method, the read-in file address is quoted, and you need to manually remove the quotation marks to process the file.

Test the code in Ipython: (read the address string of a picture file)

   A = input ("Input a:\n")   print "The Input method:", a   B = raw_input ("Input b:\n")   print "The Raw_input method: ", b      input A:   '/home/sunny/caffe-master/examples/images/cat.jpg ' the   Input method:/home/sunny/ Caffe-master/examples/images/cat.jpg      input B:   '/home/sunny/caffe-master/examples/images/cat.jpg '   

In addition, another visual difference between the two input methods is that input has an arithmetic processing function, that is, the input calculation will directly output the results, and Raw_input will be original (raw) output:

  #! -*-coding:utf-8-*-    print raw_input (U ' Test raw_input:\n ')
