正在尝试将此脚本的输出保存到基于csv中的单元格的文件中。我可以调用变量{file_root_name}
写入xml文件,但不能作为变量来写入文件名。如何使用变量file_root_name
作为变量生成文件名?在
import csv
import sys
from xml.etree import ElementTree
from xml.etree.ElementTree import Element, SubElement, Comment, tostring
from xml.dom import minidom
def prettify(elem):
"""Return a pretty-printed XML string for the Element.
"""
rough_string = ElementTree.tostring(elem, 'utf-8')
reparsed = minidom.parseString(rough_string)
return reparsed.toprettyxml(indent=" ", encoding = 'utf-8')
doctype = '<!DOCTYPE smil PUBLIC "-//W3C//DTD SMIL 2.0//EN" "http://www.w3.org/2001/SMIL20/SMIL20.dtd">'
video_data = ((256, 336000),
(512, 592000),
(768, 848000),
(1128, 1208000))
with open(sys.argv[1], 'rU') as f:
reader = csv.DictReader(f)
for row in reader:
root = Element('smil')
root.set('xmlns', 'http://www.w3.org/2001/SMIL20/Language')
head = SubElement(root, 'head')
meta = SubElement(head, 'meta base="rtmp://cp23636.edgefcs.net/ondemand"')
body = SubElement(root, 'body')
switch_tag = ElementTree.SubElement(body, 'switch')
for suffix, bitrate in video_data:
attrs = {'src': ("mp4:soundcheck/{year}/{id}/{file_root_name}_{suffix}.mp4"
.format(suffix=str(suffix), **row)),
'system-bitrate': str(bitrate),
}
ElementTree.SubElement(switch_tag, 'video', attrs)
xml, doc = prettify(root).split('\n', 1)
output = open('file_root_name'+'.smil', 'w')
output.write(xml + doctype + doc)
output.close
我不确定我是否会遵守,但是如果
works则“file_root_name”必须是dictlike对象行的字符串键。线
^{pr2}$实际上,文件名与'em'组合在一起。所以你真的想要
顺便说一句,排队
^{4}$不会做任何你想做的事输出.关闭()或者干脆
