Python3使用csv模块csv.writer().writerow()保存csv文件,产生空行的问题

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

一开始的代码如下:


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:
