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:
