问题：csv.writer().writerow()保存的csv文件，打开时每行后都多一行空行

def write_csv_file(path, head, data):  
    try:  
        with open(path, 'w') as csv_file:  
            writer = csv.writer(csv_file, dialect='excel')  
  
            if head is not None:  
                writer.writerow(head)  
  
            for row in data:  
                writer.writerow(row)  
  
            print("Write a CSV file to path %s Successful." % path)  
    except Exception as e:  
        print("Write an CSV file to path: %s, Case: %s" % (path, e))  

调用该方法将数据写入csv文件，打开文件后，发现写入的数据形式如下：

每一行数据后面都自动增加了一个空行。
该问题解决方法：在open()内增加一个参数newline=” 即可，更改后代码结构如下：

def write_csv_file(path, head, data):  
    try:  
        with open(path, 'w', newline='') as csv_file:  
            writer = csv.writer(csv_file, dialect='excel')  
  
            if head is not None:  
                writer.writerow(head)  
  
            for row in data:  
                writer.writerow(row)  
  
            print("Write a CSV file to path %s Successful." % path)  
    except Exception as e:  
        print("Write an CSV file to path: %s, Case: %s" % (path, e))  
        

重新执行该程序后，得到了想要的结果，结果如下：
