python统计代码行数的实现代码

代码如下：

  import sys,os    
        
    def afileline(f_path):    
        res=0    
        f=open(f_path,"r",1,"utf8")    
        for lines in f:    
            if(lines.split()):    
                res+=1    
        return res    
        
    if(__name__=='__main__'):    
        host='/root/workspace/'  
        print(host)  
        allline=0    
        allfiles=0    
        for root,dirs,files in os.walk(host):    
            if(root.startswith(host+os.sep+'adodb5')):    
                continue    
            if(root.startswith(host+os.sep+'corephpexcel')):    
                continue    
            if(root.startswith(host+os.sep+'exteditor')):    
                continue    
            for afile in files:    
                if(afile in ['PHPExcel.php', 'jquery-1.5.2.js', 'jquery-ui.js','jquery-ui.css','timer.js']):    
                    continue    
                ext=afile.split('.')    
                ext=ext[-1]    
                if(ext in ['py','xml']):    
                    itpath=root+os.sep+afile    
                    allfiles+=1    
                    allline+=afileline(itpath)    
        print ('Total lines:',allline)    
        print ('Total: ',allfiles)
