Compile a Python program to calculate the number of rows

When we use the Python programming language for program development, we will find that this powerful language can play a very important role for us. Then, we will use the implementation of a Python program to carefully analyze the uniqueness of this language.

I have been paying attention to Python and haven't written a program in Python. Today I wrote a simple Python program for code statistics at noon. Recursively search the input path, find the code file, and calculate the number of lines of comments, empty lines, and real lines of code for each code file. If you use a program, you can write it roughly without exception handling.

The main Python script file LineCount. py contains the following content:

 
 

  
  
import sys;  
  
  
import os;  
  
  
class LineCount:  
  
  
def trim(self,docstring):  
  
  
if not docstring:  
  
  
return ''  
  
  
lines = docstring.expandtabs().splitlines()  
  
  
indent = sys.maxint  
  
  
for line in lines[1:]:  
  
  
stripped = line.lstrip()  
  
  
if stripped:  
  
  
indent = min(indent, len(line) - len(stripped))  
  
  
trimmed = [lines[0].strip()]  
  
  
if indent < sys.maxint: 
  
  
for line in lines[1:]:  
  
  
trimmed.append(line[indent:].rstrip())  
  
  
while trimmed and not trimmed[-1]:  
  
  
trimmed.pop()  
  
  
while trimmed and not trimmed[0]:  
  
  
trimmed.pop(0)  
  
  
return '\n'.join(trimmed)  
  
  
def FileLineCount(self,filename):  
  
  
(filepath,tempfilename) = os.path.split(filename);  
  
  
(shotname,extension) = os.path.splitext(tempfilename);  
  
  
if extension == '.txt' or extension == '.hol' : # file type   
  
  
file = open(filename,'r');  
  
  
self.sourceFileCount += 1;  
  
  
allLines = file.readlines();  
  
  
file.close();  
  
  
lineCount =0;  
  
  
commentCount = 0;  
  
  
blankCount = 0;  
  
  
codeCount = 0;  
  
  
for eachLine in allLines:  
  
  
if eachLine != " " :  
  
  
eachLineeachLine = eachLine.replace(" ",""); #remove space  
  
  
eachLine = self.trim(eachLine); #remove tabIndent  
  
  
if eachLine.find('--') == 0 : #LINECOMMENT   
  
  
commentCount += 1;  
  
  
else :  
  
  
if eachLine == "":  
  
  
blankCount += 1;  
  
  
else :  
  
  
codeCount += 1;  
  
  
lineCountlineCount = lineCount + 1;  
  
  
self.all += lineCount;  
  
  
self.allComment += commentCount;  
  
  
self.allBlank += blankCount;  
  
  
self.allSource += codeCount;  
  
  
print filename;  
  
  
print ' Total :',lineCount ;  
  
  
print ' Comment :',commentCount;  
  
  
print ' Blank :',blankCount;  
  
  
print ' Source :',codeCount;  
  
  
def CalulateCodeCount(self,filename):  
  
  
if os.path.isdir(filename) :  
  
  
if not filename.endswith('\\'):  
  
  
filename += '\\';   
  
  
for file in os.listdir(filename):  
  
  
if os.path.isdir(filename + file):  
  
  
self.CalulateCodeCount(filename + file);  
  
  
else:  
  
  
self.FileLineCount(filename + file);  
  
  
else:  
  
  
self.FileLineCount(filename);  
  
  
# Open File  
  
  
def __init__(self):  
  
  
self.all = 0;  
  
  
self.allComment =0;  
  
  
self.allBlank = 0;  
  
  
self.allSource = 0;  
  
  
self.sourceFileCount = 0;  
  
  
filename = raw_input('Enter file name: ');  
  
  
self.CalulateCodeCount(filename);  
  
  
if self.sourceFileCount == 0 :  
  
  
print 'No Code File';  
  
  
pass;  
  
  
print '\n';  
  
  
print '***************** All Files **********************';  
  
  
print ' Files :',self.sourceFileCount;  
  
  
print ' Total :',self.all;  
  
  
print ' Comment :',self.allComment;  
  
  
print ' Blank :',self.allBlank;  
  
  
print ' Source :',self.allSource;  
  
  
print '****************************************************';  
  
  
myLineCount = LineCount(); 
 
 

We can see that extension = '.txt 'or extension ='. hol 'is used to determine the file suffix and determine whether to calculate the number of lines of code. If eachLine. find ('--') = 0: This sentence is used to determine whether the current row is a single line comment. Our language does not support block comment ). To run on other machines, py2exe is used to generate an executable exe from the Python script. The content of the setup. py script is as follows:

 
 

  
  
from distutils.core import setup  
  
  
import py2exe  
  
  
setup(  
  
  
version = "0.0.1",  
  
  
description = "LineCount",  
  
  
name = "LineCount",  
  
  
console = ["LineCount.py"],  
  
  
) 
 
 

However, after the exe is generated, the program is too bloated, with more than 3 m. I feel that using Python is indeed a pleasant task.
