python文件处理

使用os模块,打开文件后去除后缀

def csv2txt()
    for filename in filelist:
        f=open("%s"%filename,"r")
        dest_filename=os.path.splitext(filename)[0]+".txt"
        f2=open("%s" %dest_filename,"w")
        for line in f.readlines():
            line line.strip()
            line2 line+','
            line3 line2.replace(",","\n")
            f2.write(line3)
    f.close
    f2.close        

比较两个文件是否一致,可以使用shell下的md5sum命令,比较两者的md5值,

def compare file(filename):
　　md5suml os.popen('md5sum %s' %filename).read()
　　md5sum2 os.popen('md5sum /verification/PCPreprocess %s' %filename).read()#change file dir
　　if(md5sum1.split()[0]=md5sum2.split()[0]):#只保留md5值
　　　　print("%s compare OK" %filename)
　　　　return True
　　else:
　　　　print("%s compare FAIL!!!" %filename)
　　　　return False

 

Python中主函数可以用

if __name__ == "__main__":
