我正在尝试在 input.txt 中获取这一列单词：
Suzuki music
Chinese music
Conservatory
Blue grass
Rock n roll
Rhythm
Composition
Contra
Instruments
变成这种格式：
"suzuki music", "chinese music", "conservatory music", "blue grass", "rock n roll", "rhythm"...
这段代码：
with open ('artsplus_stuff.txt', 'r') as f:
list.append(", ".join(['%s' % row for row in f.read().splitlines()]))
for item in list:
item.lower()
print list
返回一个列表，但第一个字母大写。
['铃木音乐、中国音乐、音乐学院、蓝草、摇滚、节奏、作曲、魂斗罗、乐器']
如何使所有项目都小写？
谢谢！
