Count Python code lines

The Addhosts project is nearing the end, and I would like to know how many lines of code we have written.

First, the demand

The number of code lines for the py file in the source directory.

650) this.width=650; "src=" Https://s3.51cto.com/oss/201711/15/16a2284fa7175bc6f107b02959024ff6.png "title=" Codedir.png "alt=" 16a2284fa7175bc6f107b02959024ff6.png "/>

Second, the script analysis

Gets all the. py files in the specified directory, traversing the files;

Read each file, traverse the contents of the file, filter out empty lines and comments;

III. realization and Results

#coding: Utf-8import osclass statlines (object):     def __init__ (Self,path):         self.path = path    def  Stat_lines (self):         file_list = os.listdir (Self.path)         os.chdir (Self.path)          total = 0        for file in file_list:             if file.endswith ('. Py '):                 lines =  Open (file, encoding= ' utf-8 '). ReadLines ()                  count = 0                 for line in lines:                     if line ==  ' \ n ':                          continue                     elif line.startswith (' # '):                         continue                      else:                         count += 1                 total += count                 print ('%s has %d lines '  % (file,count))         print (' total lines is: %d '  %total) if  __name__ ==  ' __main__ ':     sl = statlines (' E:\\Python_Project\\addhost _v2\\addhosts ')     sl.stat_lines ()

The results of the operation are as follows:

650) this.width=650; "src=" Https://s3.51cto.com/oss/201711/15/cc2ac41637ba3f31728df8ad7e07162a.png "title=" Results.png "alt=" Cc2ac41637ba3f31728df8ad7e07162a.png "/>

Iv. Summary

Questions:

The following error was encountered while executing open (file). ReadLines ()

"Unicodedecodeerror: ' GBK ' codec can ' t decode byte 0xaf in position 548:illegal multibyte sequence"

Workaround:

After setting encoding= ' Utf-8 ' in open, the problem is resolved.
